I having difficulties getting an XP Pro machine on my LAN to share it's printer. I've traced the problem down to having
an undefined Local Policies | User Rights Assignment | Access this computer from the network. When I add any user or
group account to the policy the system will erase the account within five minutes. I can use the printer remotely for
the few minutes before the value is removed.

Why is the system removing the value?

This machine used to be part of a domain and I removed it from the domain. It is now just part of a workgroup. I also
modified some values in the LSP but I don't see what would have caused the problem. I also installed MS Antispyware
beta, which I have since removed.

Any ideas would be greatly appreciated.
