Issue in Brief: Unable to add node back to the cluster.

Details of the issue: We noticed that one of the nodes in the two node cluster(node & disk majority) is 'down' in FCM.  However, we're able to ping it from another node and also RDP into it.

Troubleshooting Performed:
-Tried to evict and re-add the problematic node to the cluster, but unsuccessful in doing so - both via. PowerShell and via. GUI.
-Also rebooted the node, and performed the above operation.  Still no luck.
  Error: Unable to successfully cleanup.
-Applied "Clear-ClusterNode" and it was successful.
-Then, tried to re-add the node but received the same error, but through GUI & PowerShell.
-Rebooted the problematic node; still getting the same error.
-Upon further investigation, we noticed that  the "CLUSDB" was missing in the registry of the problematic node.
-Copied the database to the problematic node (from the other node), and tried to load it in the registry, without success.
-Then copied the "CLUSDB.blf" file to the location, renamed it to "CLUSDB" and tried to add the node again.  Still getting the same error.

-Looked into AD, and found the appropriate CNO for the cluster, and VCOs of its corresponding nodes.

-Noticed below error in the cluster logs as part of our investigation.

"New join with n2: stage: 'Authenticate Initial Connection' status HrError(0x80090301) reason: '[SV] Authentication failed'"

-Did a "portquery" on the other node, from the problematic node and it …

 Acronis Global Cyber Summit 2019 in Miami

The Acronis Global Cyber Summit 2019 will be held at the Fontainebleau Miami Beach Resort on October 13–16, 2019, and it promises to be the must-attend event for IT infrastructure managers, CIOs, service providers, value-added resellers, ISVs, and developers.

I have a customer on a Synology 916+ with Cloud station Sync.  Laptop isn't getting ALL of the files.  So, customer gets frustrated when he goes on the road to find that the files he posts on the server aren't showing up on the laptop.  The agent doesn't continue syncing and believes that it's finished syncronizing.  I've seen complaints on the Synology forum with no specific answers.

Anyone have experience with this problem?

We have been trying to deal with this password prompt for quite a while now and for a period of time we were pointing the blame to a few add-ins. However, during today's troubleshooting I ran a little connection status test to see what it was trying to connect to during the time of the prompt. Well I found a little connection that stood out where it was trying to connect in cache mode. I decided to turn cached exchange mode off and ever since then I have not gotten a password prompt. After restarting outlook about 50 or so times I decided it was enough and tried to re-enable the cached exchange mode, and as I expected, the password prompts started coming back.

So what could be causing cached exchange mode in outlook H&B 2016 to to prompt for these windows credentials? I saw one spiceworks article where a guy was basically saying that cached mode might be connecting the public FQDN instead of the private network name and it prompts because it sees the server as being outside of the logged in domain? Just looking for a possible resolution so that we can still keep exchange mode enabled for the benefits it provides.

I have firewall that blocks some IP's from accessing the Internet that works fine. When an user comes in from the VPN they are able to access any devices except the devices that are being blocked from Internet access. I would like help troubleshooting or creating a policy that will keep the network devices from access the internet but when an user logs into the vpn they are able to access the devices.

I have a single user that cannot get their mobile device to connect to exchange active sync. We have a policy that quarantines all new devices so I can approve them as soon as the user lets me know they have connected the device.

Troubleshooting I have performed:
1. Attempted using another device. No Quarantine notification and unable to sync.
2. Disabled the mailbox and purged from the DB.
3. Re-created the users email account and still unable to sync with devices or get quarantine.
4. Wiped the device and attempted to reconnect still unable to get quarantine.
5. Deleted the account in AD and Exchange.
6. Re-created the account and unable to connect.
7. Created a test account and am able to connect.

Im really at a loss as to why this account will not allow devices to connect to active sync. Its a single account of 2100.

My organization has been having an issue for a few months now where a user will try to unlock their Windows 10 computer but no field populates to enter their password.  Sometimes the username will appear, other times nothing will appear.  On the lock screen you can see the date and time, but once you hit enter, it goes blank (you can still see the lock screen wallpaper).  A simple restart will fix this, however at the rate this is happening that is only a work around, and if the user has an unsaved document that presents a problem.  The troubleshooting steps I’ve tried based on my own research have been to disable Fast Start under Power settings and to make a registry edit which disables the lock screen.  Disabling Fast Start had no effect and disabling the lock screen seems to at best lessened the frequency of the issue occurring to once every two or three weeks.

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 …

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.

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


   Set molNS = …

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 :-)
