Just wanted to share big mistake I made today while implementing UTM in a client's company.
I have prepared UTM earlier in my office using public FQDN name in setup wizard - mail.company.com.
On a client site I have forgot to change UTM DNS hostname before joining it to domain, so UTM joined to domain with computer account name of MAIL. That was the same name as internal Exchange server, so I broke domain trust relationship between that server and AD...[;)]
Solution was to turn off UTM, run this command, and reboot server:
[FONT="Courier New"]netdom resetpwd /s[:D]c.company.com /ud:company\Administrator /pd: password[/FONT]
UTM went back to the table..[:)]
