it seems there are some problem on contacting the DC.

try to check the following things
1) the dns of the clients point to the still alive DC
2) check the same for the exchange server
3) if you make some changes maybe u wil lhave to reboot the exchange server.
4) check in theactive directory users and computers if the users that have this problem are correct

let me know

Is the other DC (I assume you have at least one ;) ) not having DNS or AD-troubles? Did you check the logs on that server?

Logging onto the exchange server is taking ages.
I've tried removing an email profile on one machine and re-adding, but it can't seem to resolve the name.

Even though pinging the name of the exchange server resolves the correct IP.

When demoting the DC, DNS was removed.

I reinstalled and added the zones as secondary zones. But forgot to enable zone transfers from the new primary DC.
Have done so now, will leave it a while and see if this resolves the issues.

Run this from the DC it's trying to connect to.


extract to a folder
start > run > cmd
cd - to that folder

adfind -sc c:DC_NAME > c:\adfold-dc.txt
adfind -sc c:EXCHANGESERVER > c:\adfnew-dc.txt

Your comment on checking the logs led me to an error.
