How to find the Actual Logon Domain Name of a Client Computer

The following knowledgebase will show you how to find a client’s actual domain name on which client has logged on successfully.

By typing Net Config Workstation you can see the domain name. The output will be:

clip_image002

The “Logon domain” in above output shows the domain name on which client has logged on successfully. This domain controller of this domain has logged on client successfully. This also shows that there is trust relationship between child and parent domains.

You can also search the following registry key to check which DNS Domain name was used by the Group Policy:

HKLM\Software\Microsoft\Windows\CurrentVersion\Group Policy\History.

You can see the DCName in the right pane which contains the DNS Domain name of client machine.

Windows Update – Continued…

You can try to register the following DLLs if Windows Update service is not starting up or having some issue updating/running Windows Updates:

 1. Create a batch file and copy the following DLL into the batch file and then double to register the following modules.

regsvr32 c:\windows\system32\vbscript.dll
regsvr32 c:\windows\system32\mshtml.dll
regsvr32 c:\windows\system32\msjava.dll
regsvr32 c:\windows\system32\jscript.dll
regsvr32 c:\windows\system32\msxml.dll
regsvr32 c:\windows\system32\actxprxy.dll
regsvr32 c:\windows\system32\shdocvw.dll

2. Restart the Windows Update and Automatic service

3. Stop the Cryptographic Service

4. Remove the folder \Windows\System32\Catroot2

5. Rename the \Windows\SoftwareDistribution folder.

 

This above folder is the restoring point for Windows Update service.

 

6. Now restart the Cryptographic Service.

7. Create another batch file and put the following lines in it and then double click on it to register the modules:

regsvr32 /s Softpub.dll
regsvr32 /s Mssip32.dll
regsvr32 /s Initpki.dll
regsvr32 softpub.dll
regsvr32 wintrust.dll

Your Windows Update should work.

How do you check if Windows is updating or not?

Users at technical board ask me many questions related to Windows Updates. They are much worried about networked computers/servers and keep asking questions related to that at boards.

I have been asked many times by users about Windows Updates. A question is still roaming in there mind about Windows Updates – this is whether my server is getting updates or not ! This is really a big challenge in computing environment to keep your computer upto date. If you delay for one day, a virus or hacker may infiltrate and disturb your whole network.

There are many ways to check it. Here are couple of them:

1. Using Registry – you can navigate to the following location in registry and check for Article or Hot Fix no. applied to the computer. If its there that means Hot Fix or updates have been applied successfully.HKLM\Software\Microsoft\updates\Windowsxxxx\ —>>> check out the list of updates being applied.

2. Using Psinfo.exe from Sysinternals. You can download it from Microsoft site or Internet. You can run this exe on a specified computer and it will give you a list of hot fix or updated installed on that computer. 

3. Using Add/Remove Programs in Control Panel, you can see the list of updates installed as software programs.

4. You can also check the Windows Update log file. This file gives you information about all the Hot Fix and updates being applied on the server.

Citrix Presentation Server 4.0 issue with Windows 2003

Couples of forums are going through an issue for Citrix Presentation Server 4.0. This issue is related to Citrix and Microsoft both. Windows is causing a STOP error on servers having Citrix Presentation Server installed. This is caused because of a conflict between Win32k.sys and WDICA.sys module of Citrix.

Currently Citrix is handling all the cases one by one and then supply a private hotfix as the replacement of WDICA.sys file. We have suffered the same and after analyzing the dump, we have found that WDICA.sys and Win32k.sys are conflicting with each other. We have unexpected shutdown on many of our production server on which Cirix Presentation Server 4.0 is installed. After analyzing memory dumps we have found that this is being caused by WDICA.sys and Win32k.sys system modules. WDICA.sys is the module being used by Citrix application and responsible for communication between Citrix Server and ICA Client. Win32k.sys is the Windows Kernel module and always active to process requests coming from other sub-components of Kernel. There was a page fault at the following address for WDICA.sys driver/module:

1. 91c84184 8082cffc 0000008e c0000005 8087bb96 nt!KeBugCheckEx+0x1b

2. 91c84548 808896e2 91c84564 00000000 91c845b8 nt!KeTerminateThread+0xee2 Thread terminated unexpectedly !

9f8 91c84668 f4515907 878b4000 91c8468c 00000000 WDICA+0x12208 91c84684 f451621e 00000200 91c846d8 88539ff8 WDICA+0x12907 91c8469c f4516500 878b4000 f452627a 878b4000 WDICA+0x1321e 00000000 00000000 00000000 00000000 00000000 WDICA+0x13500

After analyzing DC (memory area: 1,2,3,4) of module in memory.dmp generated by servers, I have found that one of the function from WDICA.sys replaced the memory area forcefully (because both the process/threads run in higher priority so anyone can replace each others memory area) used by Kernel module (Win32k.sys) and this resulted in termination of all the threads of Win32k.sys. Since Win32k.sys is a Kernel component, any termination in Kernel thread results in system crash or STOP error. After digging more into this, I found that this is an issue with both the modules. The new functions in Citrix module are conflicting with Win32k.sys while shadowing a user session from one Citrix server to another Citrix server. Users keep shadowing session for their purpose and after about 2-3 minutes one of the servers reboots with STOP error.

Solution and couple of points:

1. Its happening because of the two modules: Win32k.sys and WDICA.sys. Probably replacing WDICA.sys should be okay for now but its good to replace Win32k.sys too. A hotfix from Microsoft is available to replace the Win32k.sys module. Please note: Win32k.sys replacement is part of Service Pack 2 and Microsoft recommends to upgrade its product with latest version but one can obtain Wn32k.sys separately from Microsoft.

http://support.microsoft.com/kb/907966

2. For WDICA.sys – You should contact Citrix to obtain the old version of WDICA.sys module. The file version must be 4.0.2198.1.

3. It started since when Hotfix replaced the module WDICA.sys with latest version.

4. It happens when shadowing a user on another server. For example, Administrator is on Citrix1 shadowing a user on Citrix2 and after 2-5 minutes Citrix2 reboots with STOP error.

 

Remove terminal services license keys from client machine.

Terminal Services server issues temporary licenses to all the client machines connecting to terminal services. It is required for the terminal services to process the request in timely fashion and will generate the hardware ID to keep the licensing information for client machine. This hardware ID is stored on client machine. This hardware ID is used to check the expiry of license. If license is expired terminal services server can not re-issue license to same computer account. Generally all the temporary license are valid till 90 days.

 

There are two ways to get rid of this when a client machine needs to have access to Terminal Services session but its license has expired:

 

  1. Change the computer name.
  2. Remove the License key from client computer. 

The second method is very useful. It just requires a registry setting to be removed from client computer. The following registry settings must be removed from client computer:

 

HKLM\Software\Microsoft\MSLicensing

HardwareID

Store

LICENSxxxx

After deleting above sub-keys try connecting to your Terminal Services server you should be able to get in.
