Hi Kelvin.
You don't mention what version of Campus Manager you're running, so I'm not sure about this, but I am thinking there is a good chance you may be running into this bug:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsj99740
for which there is a workaround (documented in that link) and which is fixed in Campus Manager 5.0.2 that is included on LMS 3.0 Update:

Please download the file:
lms30_dec07_update_win_k9.zip

or if running Solaris, download the Solaris equiv.
Please take note of the readme file:

Only apply these patches if currently on LMS 3.0.
