It keeps "Importing Active Directory schema" already for 1h 20m, with CPU at 99%. And progress bar does not move.

I see related post (but not clear if they had cpu busy as well).

The "Cancel" button is disabled, and the busy process is lsass.exe. Wonder if I should kill this process, or continue waiting? And how long does it take to complete this operation normally?

I did it last night... SP3, though. It took 22 minutes.

I stopped my vmware, added some more memory (396 mb -> 512 mb) and restarted installer after reboot. Now it imported schema in 12 mins. I checked the logs, the previous time it stucked on schema 80. – alex2k8 Jul 11 '10 at 14:18
No wonder it was getting stuck with 396 MB... that's absolutely not enough for Exchange 2007 on a DC. Or for Exchange 2007 at all. – Massimo Jul 11 '10 at 15:32
Our Exchange 2007 server consumes 5Gb and that's for 10 users... – Mark Henderson Jul 12 '10 at 2:18

1) Why are you using the x86 version? Is it a test environment?
2) Why Exchange 2007 SP1? You should really use SP3.
3) Are you installing it on a domain controller?
4) What hardware are you using?
5) Which operating system?


6) No, you most definitely should not kill lsass.exe. NEVER. It's a critical system process.

BTW, probably I was not clear... I am installing Exchange Server 2007 with SP 1, not a Service Pack. – alex2k8 Jul 11 '10 at 14:01
@alex2k8, it's the same thing, you can do a full install from a "service pack" download. It's not a standalone service pack installer. – ThatGraemeGuy Jul 11 '10 at 15:10
