Thanks for the info, knowing where it came for is now even more important as I have discovered: The PCs with .7003 that work have a different .dll the those that do not! A checksum of the two files turns out different. It is possible using groupwise to see a plain text version of the file and there are differences despite the fact that the text in both indicates they are the same version. I am losing access to groupwise today, is there another app that can do this? BTW - I can attach the two files here if anyone cares for their own couriosity. I am trying to find out if this 'broken' version came from a different source & if so where. Why two files would have the same version number if they are different. I'd love to know why this has never been a problem until we tried to impliment a web based vpn. Sadly the vpn vendor is just happy I solved the problem that they don't care why. Seems short-sighted to me but hey I'm not a multi-billion dollar giant.
