Slow logon to Citrix XA6 published Desktop (windows server 2008 R2)  - Internet explorer branding policy

Posted on 2012-03-29

Hi Guys,
I was looking for some expert advice. We have 5 Citrix servers in a farm using TS Roaming profiles. When a user logs into Citrix the log in process hangs for 1 minute on the internet explorer branding policy part. Now I have looked at several threads online regarding this issue and found several other people with the same problem. We are using internet explorer 8 but I have also tested it on a test server with ie9 and still with the same results.

I used GPLOGVIEW to find out what is happening and confirmed that it is the Branding policy that hangs.

To try and correct it I did the follwoing:

- Disabled all the GPOs that had any branding settings
- Added the reg key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_PARSING_BRANDING_CMDLINE_FLAGS_KB941158

I found references to a DLL file but I could not get a version that would work on our server as our server is 64bit.(iedkcs32.dll)

Is there anyone out there that knows or has been through this problem before?

Have you tried opening a command prompt as administrator and typing rundll32 iedkcs32.dll;Clear ?

Do you have folder redirection set? Try adding the following key on the client PCs:


Inside that key add '*' as a REG_DWORD with value of 1.

Note you add the character * without the quotes.

I have published desktops that had a similar issue and found using group policy preferences caused our slow logons.  We could not stop using the preferences so we found a work around.  Each session logon causes files/folders to be written to C:\ProgramData\Microsoft\Group Policy\History.  After a while there are thousands of files in there and each is enumerated during the logon process.  We set this simple script to run everyday to clear the directory and the user complaints went way down.

rd "C:\ProgramData\Microsoft\Group Policy\History" /s /q

rundll32 iedkcs32.dll;Clear did not work.

Also we have folder redirection but how does the client affect this?

lastly clearing "C:\ProgramData\Microsoft\Group Policy\History" did not work

If you have folder redirection then that's fine.

However, did you apply the registry setting I proposed?
