Hey everyone -- I originally came to Experts' Exchange to address a bedeviling c0000218 blue-screen error, but the discussion has kind of splintered a bit, so I'm going to open a new question.

In the original question, the consensus seems to be that the Ultimate Boot CD for Windows (UBCD4Win) is the best method of repairing the registry error which is preventing me from booting my computer. The original source for the program is now defunct, but it still exists around the Internet largely as freeware. Though I'm convinced that the program may end up doing the job I need, it's been a bedeviling journey just to create the necessary file(s) to carry out the process. Several attempts to create or use the program have not ended successfully so far, and I'm at wits end to understand why. I will detail one of the more recent attempts below; to follow some of the previous attempts, start with this comment on my other question; you could work upward or downward from there, I guess.

After a recent failed attempt to build an .iso file from the program, I took a closer look at the log and found a pair of errors which caused the build to fail. As suggested by another forum user who commented on my update to the original topic, it turns out that the Windows XP operating system I'd been using to facilitate the build was corrupted by a couple of missing registry files, as the image below will show.

Hi Experts,

since yesterday we have some strange issues with WIN10 machines.
When the user logs in, the screen is black and you cannot click anything.
We have checked the monitors and cables, all ok.
Do you have any infos about this ?

When I check the services from this machine, I can see a lot of services are in starting modus.
See the screenshot.

Accessing C$ on the network:

I have various reasons for needing to do this.  
One has to do with testing / confirming / troubleshooting access from monitoring "server workstations" using things like EventLog Analyzer and GFI Languard.

Here is the situation:
Each computer is on a peer-to-peer network and has a common Admin1 User/Password.  The server workstation is logged in with that User.
Using UAC \\[target_ipaddress]\C$ from the server workstation generally works.
But, on some target workstations it does not.
So, the task is to resolve the failures and turn them into successes.

Since all of these workstations have been treated fairly equally regarding file sharing, firewall settings, services, etc. it's surprising when failures occur. and I'm hard pressed to find a solution.  
I keep asking myself "what's different?"  and, while willing,  end up searching rather involved descriptions of things that I probably don't need to investigate in such detail.  

There are other aspects but to be fair to the Experts, I'll ask them separately.
But, in this case I'll add that the workstations are in 3 subnets each in workgroups named identically WORKGROUP - routed together with no NetBIOS traffic allowed; there is no inter-subnet name service.
Yet, the services I'm trying to troubleshoot DO work across all 3 subnets - just not in every target computer.
(In some cases I'm sure that the checklist of things to "fix" to get the monitoring to work is bigger than it …

SBS2011 getting ready to replace the server, in the meantime DNS resolution is horrible however I'm not convinced it's the server I think it's on the ISP side. When I ping either DNS server from the ISP it has a lag well above 25ms to 35ms. This is not enough though to determine why DNS resolution is so slow and the reason for this post. How to proceed troubleshooting in this case.

SBS2011 doesn't use forwarders but I tried them anyway without any luck. I also added 8.8.8.8 for testing purposes and nothing changed. SBS2011 DNS/DHCP is configure, without forwarders and is using root hints. Firewall is using DNS from the ISP.

Something strange, when I make a VPN connection my resolution is fine. I may not be fully understanding DNS through a VPN connection, my understanding is I'm routed through the server so shouldn't I see the same issues? Note, I'm not using SBS routing and remote access using L2TP on the firewall. Maybe I just answers my question and I'm routing around the SBS2011 Server.

Also upgrade the bandwidth which is nice, much faster but the DNS resolution is still extremely slow and an issue.

I have an NEC DT700 series phone. I think specifically it is a DT730.

Right now the message light is blinking, but the voice mailbox is empty.  It also has "MSG >>>" on the screen.

There is "Frontdesk" as the identifier, but I cannot clear that off.

Hello.

I want to create a trigger on a table on INSERT. So when an INSERT attempts to happen on the table, a SELECT is first run and if the SELECT returns rows, the INSERT is cancelled but the transaction ls logged to another table.

The code that has the SELECT in, is as follows

BEGIN TRAN
IF (EXISTS (SELECT *
FROM DBO.TABLE1 AS A, DBO.TABLE2 AS B 
WHERE A.ACCOUNTID = B.ACCOUNTID
AND A.COUPONID = B.COUPONID
AND PREVBALANCE = 4 AND BALANCE = -2
AND ISSUEDLOCALDATE> '3-JUL-2018'))
BEGIN 
	SELECT @@TRANCOUNT,'UNABLE TO UPDATE TABLE 1 WITH THESE DETAILS - CHECK TABLE_ISSUE' 
	ROLLBACK
END

Open in new window



The above works as expected.

I'm now trying to develop a trigger on the table in question:


USE [DB]
GO
/****** Object:  Trigger [dbo].[TRIG_WIDGET_ADDITIONAL_COUPON_ISSUE]    Script Date: 08/16/2018 09:41:50 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[TRIG_WIDGET_ADDITIONAL_COUPON_ISSUE]   
ON [dbo].[WIDGET_COUPON]   
AFTER INSERT 
AS 

	DECLARE @inserted TABLE ([couponID] [bigint] NOT NULL,[organizationID] [bigint] NOT NULL, [orgLevelID] [bigint] NULL, [couponTypeID] [bigint] NULL, [accountID] [bigint] NULL,	[promotionID] [bigint] NULL,[customerID] [bigint] NULL,[hashCode] [int] NULL,[couponCode] [nvarchar](32) NULL DEFAULT ((0)),[serialNumber] [nvarchar](50) NOT NULL,[createdLocalDateTime] [datetime] NOT NULL,[createdHostDateTime] [datetime] NOT NULL,[createdLocationID] [int] NULL,[issuedLocalDateTime] [datetime]

Plan to purchase a network troubleshooting tool. This tool is one of the more popular brands on the market. It is the inline version. Our company is  using a Cisco switch network environment. Our switches are configured for port security using “Sticky Macs” with a maximum of 2 addresses allowed. One for computers and the second for IP phones.

My question is are these inline testers useful or useless in a Cisco port security network. I have been told that these type testers have MAC addresses that will “trip” port security  and render the tester virtually useless. My main purpose for inquiring about this tester is when I attempt to trace cables runs to identify and display what interface the cable is connected to on the switch.

Also, another issue is, that because some of these switch are configured with port security and ACL list, the port under investigation may be  “ shut down or inactive”. Will this popular network tester indentify and locate interfaces on the switch that are INACTIVE?
The cable run from the patch panel to the switches in out closets are a complete mess!
It looks like a giant plate of spaghetti!!! I am quite sure you know what I am talking about!
As a result it is very difficult to trace the Ethernet patch cable “all the way” to the end point on the switch panel. Most times I have to take an educated guess when trying “see” where exactly the cable goes into the interface.

And finally, is there a network tool on the market that will,do what I …

Hello. I am troubleshooting a WYSE Thin Client with Win Embedded Standard 7.  Earlier yesterday, I got the error" Failed to Connect to MQTT Server! twice. I'm stumped at the moment as to why that is happening. It isn't affecting the home user to where she can't log into RDP, etc, I simply want to know how I can rectify this error from coming up in my Events tab on the Wyse Management Suite. Thanks!

Hi,

When i move this user mailbox from db1 to db4 which encountered this error:

Property expression ‘user1’ isn’t valid values are: Strings that includes @, cannot be the last character

Troubleshoot.

1. Checked user at AD and confirmed no space and invalid character
2. Checked ADSI Edit > OU=OP > OU=Mail > CN=user1 no invlid character
3. Checked user can login to the outlook and OWA without any issue like file corruption


How to troubleshooting and can move user mailbox without this issue.


If need to run powershell, can i understand where to run it and what will be the easy command for me that never used powershell. Run In exchange 2010 or PC with Powershell login with import-module.  

Tks.

Power outage created a mess with Exchange and auto discovery issues since. After power outage cycled on a 2012 Sever Standard with two VM's, 1. PDC 2. Exchange. After server came up Exchange doesn't allow auto-discover and Outlook clients don't connect. First problem was noticed when all Outlook clients reported "Trying to connect" to the Exchange server. For troubleshooting purposes I deleted an Outlook profile and get the following trying to create a new profile.
errorerror2Some certs were replaced and we believe the problem may be here, we're looking at certs and will follow up. Another interesting issue is the IP address on the exchange server was hardcoded before the server restart. However after the power outage when the server restarts in DNS and the "Network" tab on the VM show a different IP address, it's dynamic rather than the static. Tried to get things working with the static IP however Exchange will not work at all this way. Changed the static IP address on the Exchange server to DHCP and it works with OWA only. Outlook clients still won't connect. With auto-discovery not working all phones have disconnected, this likely will change after auto-discover is working again.

Currently Troubleshooting an issue on our file server with a large share where I as an admin via any commputer am unable to copy or save changes to the share.

Will having the read only check box affect users from copying or making changes to files\folder  in the sub folders on a network share? Event though Ntfs permissions and share permissions have been set accordingly.

Hello Experts

I am searching for emails in Outlook 2010 from Access 2010 VBA and want to use the AdvancedSearch method.
I know that the email I am searching for exists because I can see it in the Deleted Items folder. However, after at least 30 minutes of searching, AdvancedSearch hasn’t yet found it. The AdvancedSearchComplete event hasn’t yet fired (or if it has I haven’t detected it) and the search result set is empty. After this time, I find it hard to believe that sheer slowness is the problem.
Some more details:

1.      All the action is occurring in the Access class module for my email management form. In the form’s module header, I declare a WithEvents reference to my desktop Outlook instance, which I check is up and running, along with some related stuff:
Private WithEvents molApp As Outlook.Application      ‘ in class module header
Private mblnIsSearchComplete As Boolean   ' set True when email search completes

Private molNS As Outlook.NameSpace
Private molFldrBase As Outlook.Folder
Private WithEvents molFldrInbox As Outlook.Folder
Private WithEvents molFldrDeleted As Outlook.Folder
Private WithEvents molInboxItems As Outlook.Items


2.      In the Form_Open event handler, I set up the necessary references, first to Outlook, which I check is up and running, and then to key email folders:
  Set molApp = GetObject(, "Outlook.Application")  ' will raise error if not already running
   mblnIsSearchComplete = False

I am trying to provide access to a camera on a remote network for a user by configuring VLAN on various L3 HP switches. The network I am working in has numerous VLANs and the path from the device to the camera crosses at least 4 L3 switches. I have been unable to get the connection to work and at this point need troubleshooting tips and a better understanding of how this should work.

At this point I would like to focus on a suggested methodology to troubleshoot connectivity on a VLAN. I have been told ping will not work because this is a L2 VLAN not intended to be routed from everything and that is why ping will not work, I think this is nonsense but please let me know if there is a way to track the VLAN path to see where the disconnect might be. Also, there has to be a L3 component as the source and destination networks are different and the route to the destination is specified on an L3 route table.


The following is the basic configuration:

Device :
Attaches to Switch 1 in VLAN 13 using an untagged (access) port. The PVID (native) VLAN on the configured port is 13.
There is no VLAN 13 interface configured on Switch 1. Using NDP and routing tables, I know that Switch 1 connects to Switch 2 using Tagged (Trunk) ports that include VLAN 13.
Switch 2 does not have an interface configured for VLAN 13.
I am unable to ping the camera from Switch 1 or Switch 2. There are no ARP entries for VLAN 13 in Switch 1. There are VLAN 13 entries in the ARP table on Switch …

I had this question after viewing STOP: c0000218 (Registry File Failure) - Windows 2000 Server.

Hello everyone...after consulting with a few other forums on this topic, with limited success, I am hoping to find a definitive solution here on the Experts Exchange.

Having posted a number of topics on this issue elsewhere, I'll keep it brief: I have an HP Vectra desktop computer that runs Windows 2000 Professional, but the device was stricken with the c0000218 "Blue Screen Of Death" back in 2010. With the help of some online computer-repair forum users elsewhere, I've managed to make some progress in trying to troubleshoot the error In the past year-plus, but have unfortunately hit a bit of a standstill in the process, and no other forum users have been able to help me move forward. Which finally brings me here to the Experts Exchange page. To save some trouble, I will provide links to the other forum topics I've started, some of which have screen captures to illustrate my progress, at the bottom of this post.

Fortunately, much of the hard work has already been done by myself with the help of the other forums' users, so hopefully, that one helpful tip to get through my logjam can come from any one of you here on this site.

Thanks in advance for any helpful replies :-)

Backstory:  I did not configure this.  This configuration was already in place for the most part.  The only thing I changed was the priority queue percentages.  The markings were already in place.
