Issue: RPC Server unavailable
I know I'm getting the above error because the Laptop cannot find the DC because I am trying to logon to the domain from a different network over a vpn. This error happens on those 'branch' networks that have their own DC and a different domain. i.e. I am loging on to a laptop on the ABC domain but the branch network I'm currently on is on the XYZ domain. nslookup is clearly not able to find the right DC which is at the other end of the branch VPN.
I have made entries in LMHOSTS to compensate but this does not work in this situation. I obviously cannot make the ABC domain DNS server the primary LAN side DNS entry on the XYZ domain. So to clarify;
- Laptop configured for logon to ABC domain is traveling to branch Network on XYZ domain
- Laptop user logs on the Laptop to be authenticated over vpn on the ABC DC
- ABC DC is not visible so RPC Server not available
Curious, other than the obvious, what do others do as a permanent solution to fix this?
