I've faced the same problem like asiasoft.I'm using Exchange 5.0 SP2 attached to WinNT server.I've tried to run the isinteg-patch and I thought I've solved the problem but seems like all my previous email was change as a image file. I can't even open the email and all the email only left the subject line highlighted but cannot be view.
I'd ran certain patches which I've downloaded from MSDN support site like the hotfix.exe but seems like even worst than the beginning. Some of the services cannot start and I've to restore the private and public information store file.
Others than that, I've tried before the link provided by
slink9 and it doesn't help at all.
Right now, my NT server still slow and the store.exe CPU usage reached to 99%. The range is from 88-99%. I've tried uninstalled the antivirus and reinstalled the antivirus program to monitor the situation but it doesn't solve the problem. Right now even worst, I can't start the NAV for MSExchange server. Please help.....thanks in advance.
