I have a 2003 SBS w sp1. We have a Watchguard Soho 6 router. I opened ports 47 and 1723 in the router for VPN. I enabled Routing and Remote Access on the server and set 10 ports for PPTP and 10 ports for L2TP. All the in house client systems run XP w/sp2 and connect using a 3COM wireless access point.
It was on a Friday when I enabled RRAS and realized that our ISP was giving us a IP using DHCP from their router. It was Monday before they assigned us a fixed IP and opened up their router as a pass through to let us controll the ports. THe workstations were shutdown over the weekend and restarted on Monday without any problems or delay. When I got the fixed IP about noon Monday, I configured the Soho router. I had an outside person check the VPN for connection which worked ok. I then took one of the workstations, an HP notebook offsite to test the VPN and access to Exchange and other network resources. Everything worked great. I shut down the notebook and took it back to the office.
Back at the office, the notebook booted and was able to login to the domain in about 5 seconds. I noticed the the system needed some updates which I downloaded, installed and restarted the system without any problems. I then rebooted one of the other notebooks and noticed that it took about 2 minutes to login and another minute to load personal settings. This started to raise some concerns. I left it running for a system scan for virus. The next day all the clients had delays in login and loading. I noticed that after they finially loaded, they couldn’t get to exchange. The one system that I used to test the VPN worked ok. After troubleshooting I finally stopped the RRAS service and everything started working OK.
One user had his notebook offsite when all of this took place. When he came back, he could login (with RRAS off), but he could not view any web pages. We could ping mit.edu and the address would display but it would not return. Which proved that the DNS was working. The other workstations could ping and view pages. I disabled RRAS to see it this was causing the problems. Still could not ping. I replaced the router and he was able to view pages and download email from a POP3 account. With the new router, I setup RRAS again and I have the same login problems, but everyone can view pages and get email.
THe problem, with RRAS on, the network gets lost. I’ve looked and cannot find any answers to the problem. Any suggestions will be most helpful.
