We get calls from people who cannot get to a website, say  The cursor will just spin and the request will time out.  This happens intermittently.  We called level 2 support, and they claim that the requests are not hitting their gateway, but I am not sure this is the case.  I'd like to provide some hard data to level 2 support with a tool like wireshark, but I don't know how to interpret wireshark.

Is there a tool that is a bit simpler than wireshark that can tell me where exactly where the hold up is?  I have looked at a tool called DNSQuerySniffer, but it looks like it stops at my internal DNS server.  I have also tried a simple tracert, but tracert hops timeout on sites that are working, so they are not reliable.  

We do have company internet filters in place (fortinet), but they are managed at level 2 so I don't have access to their logs.  I am also told that there are a few old DNS server records in my forward lookup zones, but they have been there long before this problem began.  

Thank you!!

In an environment w/o roaming profiles:  Some computers have multiple users & accumulate too many profiles.  Users fail to use their Network Drive adding files to these profiles.  What's the best way to force a single profile on all who login on those machines and force a mapping of at least the Documents Folder to the users network drive?  (For both Win7 & Win10.
Windows 7 pro computers in peer-to-peer network.  All computers were accessing shared files well 'until' i ran DELL Support Assist program. Updated BIOS as well as network adapter drivers on all ending in a utility to 'optimize' network connectivity.  Two of the computers ceased to allow access to their shared folders across the network using their Computer name \\johns PC\shared folder. I could use their IP address  \\\shared folder. I get the standard message I do not have Permission to accesss the shares...  i tried 'every' remedy I could find online...ipconfig \flush dns, replaced 'host' file...
 reinstalling network adapter drivers, reset winsock, finally Repair Reinstalled Windows 7...nothing seems to work.  i finally clean reinstsalled Windows 7 on one of the two and that worked...i want to avoid a clean install on the other Windows 7 if possible so here i am.

I have

Going the other way this computer has no issue seeing all other shares on the network, just no one can get in using the 'Browse' and 'Select' method.

I cannot telnet to idrive servers on port 443. As a result the remote backup quit working. I can telnet to on other client networks. We have a Cisco ASA 5506. Im using ADSM to try and figure this out. I have uninstalled antivirus, disabled pc firewall etc. Below is a screenshot of the rule I created to try and fix this.

I have another network that has no firewall and is wide open for testing, and I cannot telnet to it on that one either. ISP says they are not blocking that address.

Hi all,

Lately, we've had a spike in user's devices losing trust relationship with our domain (we've only one domain).

We've made no changes recently to the domain or domain controllers. Can anyone point me in the direction to what might be the cause of this and what health check I can run that might highlight what the cause is?

I am currently with Ivanti formally known as Shavlik patch management.  My 3 year is about to expire, what I was paying for 3 years is now what I will have to pay for 1 year so we can not continue with Ivanti.   Does anyone have any recommendations on a patch management system that has a reasonably  price structure?

Hi Team,
I have a project that involves moving my secondary domain controller to a cloud environment on a different not-NATed subnet. Unfortunately, in the process of doing a bare metal copy using VEEAM Agent, my DC02 came up malfunctioning, As a result of tweaking and ruminating it seemed easier to just bring the local copy of DC02 back online. My plan now is to just build a new third domain controller (DC03) and decommission the second one. My post is mostly for the sake of gathering thoughts, advice, and little-known information when it comes to setting up a new DC as this will be my first rodeo.

My current setup (IP addresses are used as an example):
DC01 ( - Primary DC (AD, DNS, DHCP, Certs) on 2008 r2 on a physical device.
DC02 ( - Secondary replicated AD and DNS on 2008 r2 in vSphere on an ESXi host.
DC03 ( - My third DC will be built in a vCloud Director environment, likely running Server 2012 or 2016. This device will also be in a different subnet, Routes have already been established and the machines that are currently there all work correctly with the devices in my local subnet.

Are there any issues replicating AD and DNS from 2008 r2 to 2012 or 2016? Would I be better off just building a 2008 r2 machine in my VCD environment, or perhaps upgrading my primary from 2008 r2 to 2012 or 2016?

What is the industry standard for setting up and configuring a third DC and then decommissioning the secondary, such as in…
Hi guys,

I got a dlink switch and synology nas.
Got link aggregation (2 ports) from switch to nas.
How do I test the performance ? Is there any way to test read write performance through link aggregation .

I just want to see the difference between a single port connection and link aggregation to either server/nas ?? Just wanted to prove a client there is a difference with actual facts!

We have a client who share data between 2 computers. PC2 connects to PC1 for shared data and some software.

Intermittently, PC2 loses connection to PC1. The share is setup as \\PC1\ Data. When we dial in, we can ping the IP address but not the PC name.

More often than not I will add a shortcut using the IP Address and then the the original shortcut using the PC name will then work. We have tried setting the shortcuts using the IP address but this had the same issue but in reverse.

I have set PC1 to static, checked Computer Browser service and UPNP are set to auto on both. Disabled all advanced sharing settings, reinstalled SMB from features and then Enabled all advanced sharing. It will work for a period of time and then lose connection again.

Any suggestions?
I have Microsoft loopback adapter set in a windows server 2016 datacenter machine.  In the past , with windows server 2008 e.t.c , I could go to Network and sharing center -> Change adapter setting -> Advanced settings   and change the order of the network adapter to give loopback adapter the highest priority. But In Windows server 2016 DC , I don't see that option. Hiw do I get it ?
I am trying to create a GPO to deploy the remote desktop connection shortcut(mstsc.exe) on all users desktops on the domain.

This is what I have:
I went into system32 and made a copy of the mstsc.exe file.
I then pasted the mstsc.exe into a share that I have on my C drive on the domain controller.
The permissions all the way through the share are everyone and domain users.
I'm starting the GPO at the root of my domain it is configured as a user policy
I am running gpudate on the DC & the client workstation.

I have included screenshots of the configuration.

I have never done this before, can someone assist me with this configuration. I will provide any additional information you may need.
Thank you.

Hi Experts

Could you point a way a Windows7 / 10 user's  login configuration could prevent an user to see network locations at Windows Explorer?

Some files needed to operation remains at network folders , the app needs to read this files during operation but the operator can't access it due security reasons.

Thanks in advance.

I'm trying to look at the VMQ setup to improve networking on our 3 node Windows Server 2016 cluster.   The cluster runs 30 virtual machines of which 6 have real time requirements as they play out radio stations.  We suffer from occasional break up on the radio streams which is usually resolved by a restart of that particular virtual machine, however I want to improve the network to all the machines if possible.  If I run Get-NetAdapterVmq I get the following results which looks like all queues are running off processor 0 which from what I've read is not good.  

However when I run the command Get-NetAdapterVmqQueue to look at how the queues are distributed I get an generic RPC error CimException with a corresponding set of logs in the Application eventlog of Event ID 1000, 1001 indicating a NetAdapterCim.dll crash when wmiprvse.exe is run, presumambly as a results of the Get command

Dear Experts

We recently deployed CRM application which is web based and deployed on windows 2012 R2  running IIS and MSSQL 2012, webserver is separate and MSSQL is separate both have enough RAM and CPU but users are experiencing slow, please suggest what could be causing this, how to do performance tuning for  IIS 8.5 and MSSQL performance tuning please suggest.
Dear Experts

We have done integration for the CRM application with external web portal, the CRM application is behind firewall and the web portal is in public cloud, integration is done through WEB API from the CRM application we able to update the records to the web portal but from the web portal records are not creating or updating in CRM application. Please help on the following
1.      As this is windows server 2012 installed with IIS how do we check the request from web portal which is from internet is hitting to CRM application.
2.      CRM application is not showing up any logs hence how to check it from windows server level and IIS
Please suggest. thanks in advance.
We have a domain controller that is being used as a file server, and has several different folders that users have mapped drives to. One of these folders has 6 users mapped to it, and it is continually disconnecting from those users on a very sporadic basis. We have added it manually, written a script to add it, and attempted a group policy, but it continually disappears from their file browser.

It is only the one shared drive, all of the others work fine. Additionally, it is not all users as of yet, but we have added it again for some of the users experiencing the problem, and it has not showed up again.
I've got a user on a MacBook Pro, who's connecting to a 2016 server via rdp 8.0, but cannot use his local printer.
Of course this all worked fine under the old 2008 terminal server, but hasn't worked with the new & improved stuff.
When trying to add the printer, I can see other macs showing up, like TS009 (Joes-MacBook-: PRN2:# 9), but am not seeeing this guy's mac listed there.
Went back to try installing printer on the server & while I see full function software & driver for all desktop OSs, the servers listed stop at 2008.
Is printer just incompatible with that server, killing the whole idea right there?
Looks like that printer is about 8 years old, is it time for a new one?
Any other work arounds?

We have a problem regarding smb shares. They are not connected sometimes. I already have a gpo which waits for a network connection but this does not help. The users needs to click on the shares to reconnect them.

Thank you in advance!
Having problems setting up a Windows 2016 Server remote desktop enviroment so the users can connect remotely. Its's a small installation with 3 - 5users so limited resources.
The setup consists of on physical server with Hyper-V on W2016 Std. and two VMs with W2016.

VM1 is AD/File/print, VM2 is TS

VM1 has the roles of Connection Broker, Gateway, Licensing and Web access VM2 is Session host.

TS works fine from the inside and from the outside if the "full adress:" parameter in the .rdp file is set to the internal adress. But the .rdp file "generated" from the https://..../RDWeb/ contains the public adress . Access to the web page is working , Sign in works ok,  the resource page with the "cpub-RD-RD-CmsRdsh.rdp " is shown, opening the logon screen pops , up OK, log into windows  gives the error "can not connect to external computer ....".
One of our clients has a shared drive. None of the computers can connect to the share, and it shows up in file browser as a media device.

I have checked the following:
- proxy disabled
- SMB and computer browser enabled
- Netbios is enabled
- Function Discovery Provider Host enabled
- Function Discovery Recourse Publication enabled
- Disabled the media sharing option in network settings

The user's computer shows the computer where the shares are in the network tab under file browser, but there is an error whenever I try to connect. I have also tried to connect through IP address and receive the same error message. The user with the issue is connected through wireless, but is on the same network.
Our local domain is the same as our web site domain. However when we try to access I get 403 forbidden access is denied. I think its pointing a local iis server or something like that. Do I need to create a DNS A record on our local DNS server to resolve this? If so what kind of record?

I am currently attempting to configure an IPSec VPN between a Zyxel USG310 Firewall and Microsoft Azure.

I have configured the connection, and it is showing as up and established as a Policy based VPN as per Zyxel guides. However I have no communication between either subnet.

On-Premise Subnet:
Azure Site Subnet:

When I ping to a VM sat within from my local site, I can see stats increasing on the outbound counter on the VPN (albeit only a tiny amount that a PING produces), however PING does not receive a response and no inbound traffic is being seen, so I am somewhat confident my outbound static route on the firewall is correct. I have configured a Policy route on the Zyxel to forward any traffic destined for to the VPN Tunnel.

Do I need to setup routing on the Azure side, or will this automatically be put in place by the creation of the Local Network Gateway and Virtual Network Gateway? I am assuming so, as this would define the return route and hence why PING is not currently working, but I am not sure where to start with this.

Any help is appreciated, thanks.
