Problem:

Running a .NET WebService on a Windows 2000 Server, that requires the machines system registry to be accessed, fails with en error message:

fail 0000000099

Resolution:

To access the system registry from a web service, you must ensure that the correct permissions are set:

1) If using IIS, check that the user iuser_machinename (where machinename is the name given to the machine) belongs to the Administrator's group.

2) Ensure that the ASP.Net user has the correct Admin permissions set.
