Network Dial up issue

I'm traveling and I am using a dial in from my laptop to our network  However, when my laptop connects I can't do anything (No log in, nothing....) I have no access and my boss wants a report of my trip before I leave Friday AM.  I can access other websites so I do not think I hane any issues with my laptop.  I have not changed anything on it since I left and it was all working fine yesterday morning.  Any assisitace would be greatly appreciated.

If it was running fine yesterday the best thing to do would be to do a system restore if the operating system on the computer is windows XP.
The above link would tell you how.
You will not loose any data, but you may loose any settings or any programs you installed after the restore date.
I know this is a dumb question, but have you rebooted your machine?
