Hi there,
actually I have a problem: I wanted to "take a look" at OpenVPN – so I installed it on my SBS 2008 Windows server. At install something went wrong with the "TAP driver", so I uninstalled OpenVPN (and the TAP driver) again. After that my Exchange services will not start anymore (Exchange IMAP4, Exchange Transport).
"The Exchange Topology service on server localhost did not return a suitable domain controller."
Translated from german: "The Exchange Active Directory could not find any availabledomain controller in domain xxx"
What does OpenVPN do on install?
Does it change my network adapter or DNS settings?
How can I get my Exchange server back to work?
Hope someone can help,
Thanks!

why would you install something that you just want to "take a look" at on a production server ? 🙂)
anyhow , if you uninstalled openvpn ... check if the tap adapter is gone from the network connections , and set your DNS server (127.0.0.1) on your LAN adapter confguration.

Yeah :-( The TAP adapter did not appear after installing. As I said, some error occured on installation. But I have uninstalled OpenVPN and uninstalled the TAP driver separately. So now it should be completely removed. In the LAN adapter the DNS setting is already pointing to this machine (192.168.178.2).

you will need to do some DNS checks for your activedirectory domain
from that machine , see if your name gets resolved by pinging it
try from another domain joined computer also
check if your DNS server is binding on the correct interface(s) , check if you have the SRV records in DNS for activedirectory
try do reboot ... this seems to fix everything with windows

Ping works via DNS (office-server.office.local -> 192.168.178.2) and reverse lookup works from another machine.
DNS server is binded to the server itself on 192.168.178.2 and the IPv6.
There are some SRV records – how do the SRV record for AD looks like?
Reboot doesn't work ;-/

I have no idea why it is working now.
I have restarted the Active Directory Servcies.
I have stopped all Exchange services and started them one by one (also Transport and IMAP worked).
It is working now... srange.

that's good , openvpn should not affect exchange server nor any other service but i would not install openvpn on a ActiveDirectory server 🙂
