accessing data base from remote computer

we have sql 2005 standard edition. i was trying ( unsuccessfully ) to configure RAS on server 2003 to allow the server to authentificate vpn requests. i don't know how but the next day people started complaining about their mapped network drives being disconnected, and now no one can connect to the database via the network, eventhough they still have access to the server, and the network drives were remapped.

Any errors or information in event log for such behaviour?

I believe this is more based on Windows side question than to SQL Server related.

|||actually now that you mention it, there is a message that keeps showing up since about the time i started playing around with RAS. it is from NfsSvr. it says mapping information could not be obtained from user mapping. another attempt will be made in 30 minutes. this message first appeared about noon on fri. however we started having trouble late thur. the message repeats itself every 30 minutes.
