I have an exchange server that is pentium IV 1.7GHz and 1GB RAM with Windows SP4 and exchange SP3.
The server was working fine with about 200 users and suddenly the process store.exe is taking 100% of CPU ! I have set the Information store servie as manual and then restart the server. The CPU usage is normal and when I start the service it again takes 100% of cpu and keeps like that. the exchange clients are not able to connect to the machine.
Please help as soon as possible
