Brace yourselves. I have the utmost worst possible situation you can imagine...
Digest version: RAID 1 array increase in space by pulling and replacing one disk in the array with a larger, to be rebuilt for later partition extension to use new available space. Result - System crashed and wouldn't reboot into OS.
Instead of doing the right thing and rebuilding from scratch, reloading from backup, the client wants a fix instead because they're unsure if they have all disks and backed up everything they might need. So I ran an attempted repair install of the OS, ended up with a parallel install and an unrecognized OS in my boot options. I was able to recover booting into the original OS by altering the boot.ini. Client still won't approve a system rebuild.
All data appears on the drive as before, but we had some website problems. Fixed those and all programs are running fine except for Exchange and Kaspersky.
I ran a restore of System State and Exchange (one at a time), and Exchange DBs are mounting, no errors in Application log, no errors in system log. However here are the problems:
When logging into OWA, everything appears initially as it should (inbox, calendar, public folders, etc.) until you click on a recent email received since the restore date. Old email prior to the restore date is viewable, new email view attempt gives the error "HTTP/1.1 503 Service Unavailable". The same applies for email view attempts in Outlook 2003. Old email can be viewed, email since restore date - No.
Also, seem to be able to receive email but not send. I've checked DNS and SMTP connector. It could be that we are running low on space as well - 5.6 GB left on the partition housing Exchange, 2.7 GB left on C drive.
Suggestions? This has been going on for a week now, and I'm exhausted. Thanks in advance!
