So today had someone who had used the 180 day trial key of MOSS to its end. Apparently their key expired while we were all grilling out this weekend whoops.
Well, no problem. Just use my blog article How do I find out when my MOSS trial expires? And it has a section on “How to update from MOSS trial to MOSS Standard or Enterprise”. Crisis averted.
Not so fast. She was now getting the error message:
Your license conversion operation failed. Check the error logs for details.
Upon looking in Event Viewer (eventvwr) she was getting
Event Type: Error
Event Source: Windows SharePoint Services 3
Event Category: Timer
Event ID: 6398
Time: 8:36:17 AM
The Execute method of job definition Microsoft.Office.Server.Administration.LicensingConversionJob (ID b535873a-5ff6-434c-b694-6e19eb40da4e) threw an exception. More information is included below.
Arithmetic operation resulted in an overflow.

Interesting…. Upon further examination it seemed that her collaboration portal was working fine but her publishing portal still thought it was using an expired trial edition. If you checked Central Administration (check above article if you need help doing this) it said everything was fine.
So how do we fix this horrible problem? IISRESET.exe
I am going to do some more digging to see if I can find out why or what happened but best I can tell all is well.
