There is a better solution. If you are using V 3.4.xx then you can look to see what your Member_ID is in the Forum_Members table. then modify line 74 (clean install) of config.asp
Const intAdminMemberID = 1
set the intAdminMemberID = to the Member_ID of your NT account. also make sure that M_Level (Forum_menbers table)is set to "4"
