I have a Windows NT 4 server with 2 NICS.  NIC1 connects to my internal network that included 3 workstations.  The NIC2 connects to a DSL model/router/firewall.  I am using Routing and Remote Access on the NT 4 server along with Sygate Internet sharing software to allow the users on the internal network to use the DWL modem to access the Internet, browse the web etc.  Although this server/network setup is antiquated, it has worked well for awhile - up until the server was inadvertantly unplugged by some.

Ever since that unexpected reboot,  users are unable to get to certain websites that they used to be able to (ex: they can go to webmail.aol.com but when they login, their connection times out,  they can go to www.hotmail.com, but after logging in, their connection times out with a DNS error).  None of the workstations on the network can access certain sites (such as aol e-mail, hotmail, etc) but all of these sites are accessible when browsing from the server.  All Internet activity is not blocked thouugh, most other sites are accessible.  I have checked my firewall/router and verified that I am not blocking ports/etc and have also looked at my routing tables/etc.  Could the unexpected server shutdown corrupted something - if so I wonder what is preventing me from only accessing certain sites

Does anyone know what my problem could be

Thanks in advance for your help
