Is Client Security Solution preventing my T60 networking?

[Muse]

Am I just better off removing the CSS in add/remove programs? I'm running XP Pro and this T60 can't be seen on the network and when I try to map a drive on a different computer in the workgroup it wants me to enter my username and a password. There's a checkbox to "Remember my password!" I've never seen that before -- I never had to enter a username and password to map a network drive. I am the administrator. I think that's the password manager in action. Is it best to disable the Thinkpad password manager (It got me in trouble before), which I think is a part of CSS, or should I just remove CSS entirely? How would I disable the Thinkpad Password Manager? None of my other computers see this T60 on the network! The T60 has a fingerprint reader. Is it necessary to leave CSS installed to make use of the FPR? I'm not that attached to it, I don't really care, but I have to get the network working.

The T60 has the factory default install of Windows XP Pro. I have made only basic changes, installing MSE, and MS Updates. When I run the network setup wizard I'm prompted with the computer name and workgroup name, which defaults to MSHOME. My workgroup name for my other computers is WORKGROUP (which is the typical default in my experience!), so I change MSHOME on this T60 to WORKGROUP and click Finish. The instructions would have me believe that I will be prompted to restart the computer to make the changes final but that doesn't happen. Even with a reboot the T60 does not appear in the workgroup for the other computers and if I run the network setup wizard again, MSHOME is again presented as the default workgroup name. Please, what's to be done here?
