We are currently in the process of migrating from Exch 2007 to Exch 2010. 2 new 2010 servers are installed and operational in the Organization. I noticed that immediately after the first Exch 2010 server installation, the OAB generation started failing with event IDs 9332 and 9126 on the generating Exchange server. At exactly the same time, Application event ID 1000 and 1015 is logged on the particular DC and this causes an unexpected crash and reboot on the DC.
Event ID 9332 on Exch 2010 server
OABGen encountered error 80040115 (internal ID 50008df) while building the address or display template files on Active Directory CPTDC02 for address list '\Global Address List' .

Event ID 9126 on Exch 2010 server
OABGen encountered error 80040115 while calculating the offline address book for address list '\Global Address List'. This offline address book won't be available for client download.

Event ID 1015 on DC
A critical system process, C:\Windows\system32\lsass.exe, failed with status code 255. The machine must now be restarted.
I suspected some permission errors in AD, so re-ran setup /preparead, runs thru successfully, but did not correct the OAB error. I have checked some object permissions in ADSIEDIT and compared them to a DC in my LAB, all seems to be more or less the same.
Anyone got any ideas?
