On clinet i have:

SNC_LIB = C:\Program Files\SAP\FrontEnd\SAPgui\gssntlm.dll and sncgss32.dll in ...\system32.

Also in sapgui i have p:DOMAIN\SAPService<SID>. I get error:

SAP system message:

'Error in the Security Network Layer'

I'm using client with Win Xp sp2 wich is in ad domain and ecc 6.0 is in workgroup. Is it possible to make snc between these two? If yes what i'm doing wrong? Wrong dll's or... i dont know...

Help me please, thx in advice.

(i'm also in digging mode and looking for solution)
