SAP GUI Error - (GSS-APP DLL) on Windows Vista!

Question

Hi All
I am getting an error when setting up SAP GUI version 710 on Windows Vista.
When I try to set up an snc logon i get the following message:
Unable to load the  GSS-API DLL named 'sncgss32.dll'
On Windows XP we have a GSSAPI32.DLL in the C drive and all is ok?
Any ideas
Thanks
Phil

The following is working on Vista at a major client in DK. It is important to know wether you use a 32bit or 64bit Operating System. This example is with 32bit system.
Create a uservariable in MS Vista called SNC_LIB. Value is <drive>:\<path>\gsskrb5.dll
example: SNC_LIB=c:\windows\system32\gsskrb5.dll
the file gsskrb5.dll should ofcourse be placed in the folder specified above. You can download the file from microsoft or from SAP (I think it can be found in a note)
The you setup your SAP environment to handle SSO with the same file in the serversetup - i recommend only to use the gsskrb5.dl file. Verify that the setup is correct on the server. If it is correct the SNC tab will exist on transaction SU01 and when you enter the correct value in the "SNC name" field the should pop up a green checkmark..
In the gui on the specific system you should enter the following value in the Secure Network setting "SAPService<system id>@<domain>".
It should work without problem.. If you have an older version of SAP you should perhaps try out the GSSNTLM.DLL file instead of GSSKRB5.DLL. That can sometimes help if it does not work.
