VPN And Domain Trusts

[stescotty]

I have a unique little issue...

We have 3 domains all 2 w2k and w3k.

All three domains are connected through a Firewall/router/VPN.
There are 3 differen ip sets.....
For arguments sake.....192.168.0.*, 192.168.123.*, and 10.101.101.* all connected by VPN.
Now connecting within this domain to terminal servers using DNS is fine.
All that leads to the main issue....we want to have a trust relationship between the 3 domains so that 1 username and password can be used between all 3 domains...however when I try to verify the trust relationships it does not find the PDC in which I am trying to Verify.

Is it something with my firewall to firewall VPN and is causing this to fail....any help would be greatly appreciated.

You might want to tell us what firewalls you're using and if you have a trust relationship setup within your AD between the three domains...

I have 3 sonicwalls all connected and running between each other by VPN.

I have also set the trust relationships between all 3 domains through AD ...but when I verify the error I get is that it could not find the PDC.

Ok...my bad I read that and it just didn't register.

Can you communicate normally among all three domains otherwise?

I think you will need to establish VPN's between each site, so site 1 VPN to site 2, site 2 VPN to site 3, site 1 to site 3. You cannot route to a non-connected sub-net via a VPN tunnel.
