inetinfo.exe uses 100% CPU

Hi Friends,

I have Backoffice Server 4.5 sp 6 installed in a netfinity 5000 Pentium II 500 128 MB RAM. In this server which is the PDC also is installed Backup exec, proxy server, IIS4. I had had the problem that in the overnight time when I cameto job I found it with inetinfo.exe using 100 % CPU and my microwave link for internet doesn’t allow users to connect and obviously the server itself becomes very slow. What could be happening? Any ideas?
