[Andy888]

Please help. My Windows 2000 server's Windows Task Manager only shows green box for CPU usage and CPU usage history. I couldn't close it and couldn't see Application and Process tags information.I restarted server and restored registry, but it is still the same. I don't know it cause by virus or not. Please help! It is my Exchange 2000 server. My exchange's memory seems leak. After a while, it it low virtual memory warnning message appear. It is almost freeze. Please help!! It is very rush!! Thanks.

Can you give me something to grasp?
No of users, RAM, CPU, disk space available and used, message throughput, event log errors, other services installed, other applications running to start with.

Thank for your reply. So far, I restored system state and double click the CPU picture. The windows Task Manager come out. But I still could not resolve the issue since last Thursday. My Exchange 2000 server has 768MB ram. Around 50 users emails account on this server. Window 2000 advance server. PIII 700mz two cpu. C drive still has 30g space. M drive (mailbox drive) still has 7G free space. Only run Exchange 2000 service. priv1.edb 17g size. It had patched exchange 2000 SP3 and rollup. Since last week, The store.exe fast glows bigger. Almost occupied all memory. The avail memory from Windows Task Manager Performance only shows 4800K. The server will slow almost freeze. When office open during the day time. It appears this situation. After office hours, I restart the server. It shows normal overnight. But during the daytime, The store.exe will glow up. Please help. Thank you.

Andy,
Are you running Exchange Enterprise? Check Event log for Exchange starting up and it says "unlimited size" if you are running Enterprise.
P3 700 is a bit slow for advanced server but other than that everything looks ok. Have you done a virus scan?
