I have a laptop running Windows XP, Service Pack 2.
I had been able to log in to a VPN system (Windows Server 2003 Standard Edition SP1) from my home office but now I am unable to do that. When I try to connect, it makes a connection, displays the `Verifying username and password? window but then says `Disconnected. Error 721: the remote computer did not respond. ?.?
If I take my laptop to another office and log in from there, it works perfectly. This leads me to believe that my problem has nothing to do with my PC settings and something to do with my router of my home office. I have Linksys router, model WRTP54G.
I have not (to the best of my knowledge) made any changes to the router since it used to work.
I do not have any idea what to look at to help resolve the problem. Is there any place I can look to help identify what is the real problem?
