Don't know where else to ask this.
I have an interesting issue on a clients server, everything works ok. But In the ESM under the servers protocols in the SMTP container the default server is missing, there are no connectors either. I have tried creating a connector to no avail. I can't create a new SMTP VS, but I can smtp to the server and send email from the server.
Nothing seems to be adversely effected though.

Anyone got any ideas? You may have seen this question asked elsewhere, as I have posted it to other MS forums to no avail.

Just some stuff that I should mention I have tried.
I have tried reinstalling exchange over the top and service packs, no go. I have tried rebuilding the IIS metabase as I have seen that fix wierd issues in ESM before. I have checked the records in AD via adsiedit as per kb933781.
I have rebooted server, and applied all available updates.
