Hi,
Recently, our SonicWall VPN began acting up. We're on a Win2K network and the clients are Win2k Pro. We have four VPN users including myself(admin). I can connect with no problems aside that it's sometime slow. My users however, log in, establish the VPN tunnel and pull an IP address from our DHCP server as normal, but if you go to a command prompt and ping the dhcp server it fails. traces fail, mapped drives obviously will not connect and Outlook does not connect to the exchange server. I can log in as Administrator on those same computers and have no problems. I've been in touch with SonicWall on this and they connect easily from tech support. They've been through the firewall and see nothing wrong. I followed their suggestion to upgrade to the latest global VPN client and first uninstalled the old client before reinstalling the new version. During the uninstall of the old client, we had to restart. I did notice one of the computers attempted to contact the internet and have become suspicious that spyware is blocking my user's profiles from connecting properly. I've also installed and run Spybot S&D, Adaware, and HijackThis in an effort to identify offending spyware and malware. After thoroughly cleaning the PCs with these utilities, I am still getting nowhere with the users VPN connections working properly. I still suspect spyware as the admin profiles have no problems on these same machines, but am at my wit's end. My users are upset as well as my supervisors. I really would appreciate any ideas on this.
I have also created host and lmhost files and am running the computers with netbios enabled over TCP/IP as recommended by SonicWall. This configuration works fine on my laptop.
Again...I would love to hear any ideas, thoughts, suggestions that will help resolve the problem.
