I have an IBM R51 Thinkpad that simply will not connect to our VPN. I have tried both Win2000 and WinXP with various service packs, hotfixes and clients (v49sp2 and 4.91) but I keep getting the same error:

The NMAS Authentication failed
Could not find the NMAS DLL/dependant DLL's

Our VPN is setup and working correctly as we have several other users that connect to it everyday. By the way, the laptop I use everyday is identical to the one I am having problems with (same BIOS, etc) and it works perfectly.

I've looked through this forum and on Novells knowledgebase, but cannot locate anything on this error.

Any ideas? Thanks!
