Re: ISA2004 kills VPN outbound

Edward,

Thanks for your attention to this, but I have a more-serious problem that I
must first address, and I would very much appreciate your help:

I have just upgraded a branch-office Windows 2000 server from ISA2000 to
ISA2004. Under ISA2000, the branch-office workstations could VPN into the
main-office VPN server and then connect via pcAnywhere to internal machines
on the main-office network. However after the upgrade to ISA2004, these same
branch-office workstations, although they successfully connect to the VPN
server, can no longer connect via pcAnywhere to the main-office
workstations. The branch-office Windows 2000 server itself can VPN into the
main-offie VPN server and connect to these main-office workstations, but the
branch-office workstations cannot.

Is it possible that you can suggest a remedy for this? My need is great.

GaryK
