A few of our staff are having problems connecting to our Exchange server from home using VPN. The peculiar thing is they can connect to the network via VPN browse the network, see the Exchange server, see the file server and print on networked printers. They can also ping the servers by both name and IP. This is happening with ~3 of say 12 persons who regularly work from home (one being our COO). Details are as follows.
OWA is working fine.
Exchange Server 2000 SP3 (with post SP3 rollup) acting as the PDC running AD.
RAS is handled by a member server handling DHCP and SUS.
Client computers are running either Win2K SP4 using Outlook 2000 SP3 or XP using Outlook XP SP2
All are connecting using Comcast Cable, Millennium Cable with a home router. All have tried connecting direct to the cable modem, direct to the router, or wireless to the router with no success.
The funny thing is that I have Comcast and have no problems connecting to Exchange across VPN using a wireless router at home. Also I have asked a few others (who have Comcast and Qwest DSL) to connect and they do not have a problem.
Any help would be appreciated.
