1. I have a win2k server with ISA on it
2. A win2k PDC with AD

I can successfully establish a VPN with the PDC internal to the network but when I try externally onto the ISA server it connects but does not authenticate (hangs on the verifying username and password).

The ISA server is registered as in the RAS and IAS Servers account on the AD users & computers.

Any help appreciated.

What kind of VPN are you using? PPTP?

If so have you enabled PPTP on the IP Packet Filters properties?

Sorry for the delay in responding... I think a may not have been clear enough.
The problem is inbound connections.

I understood that, but have you checked the PPTP on the IP Packet Filter?

No problem

Just to be sure. The VPN server is on the PDC and not on the ISA server?

That is Correct.

I can establish a VPN from within the internal network but externally (and internally via ISA external interface) it connects but hangs on the verifying username and password

All sorted now....

All I did was re-apply Win2k SP4 & ISA200 SP2
Thanks for you help anyway!
