Server is running sbs server 2003 (premium edition) sp2 with exchange 2003.
Monitoring was playing up, so followed steps to completely remove.
After removing I rebooted server and reinstalled monitoring component . during install it prompted for original windows 2003 cd3 so used that (do not have a copy of 2003 sp2 slipstreamed cd) . At the end of the install it advised that some components will not run correctly because service pack 2 disc was not used to reinstall monitoring component.
Monitoring still didn't work , had errors end of using the configuration wizard (3 out of 4 points did not successfully complete)
It advised to reinstall the service pack. Download 2003 sp2 and tried to reinstall. Then I got "Access denied" error during install. Tried to troubleshoot that by resetting default security setting as explained in a MS KB. that didn't work.
I noticed WMI errors in event log so I followed this KB to reregister the Exchange 2003 namespace with WMI(kb/288590) . Got errors while running these commands;
