RAMNX, this is how it works ( reading your last post tells me i need to explain this.)
NX out of the box has a default setting. This cannot be changed and there is no need to.
These settings can be overridden by changes to the customer defaults Site settings. ( If there is a "UGII_SITE_DIR" set on this system.)
The Site settings can be overridden by Group settings, If the Site settings allow this. ( You can lock some or all settings on Site level) ( If there is a UGII_GROUP_DIR set on this system.)
The Group and Site settings can be overridden by User settings, If Site and Group allow this. ( You can lock all or some settings on the group level.) ( Equally you can set a UGII_USER_DIR variable, if you don't set this , it will default to what John Baker wrote above.
In your system, it seems that all the users have overridden the SITE and GROUP settings. As Cowski notes, It is not intended that the regular users have write access to SITE and GROUP. If i was the system manager, i would lock the settings that i want untouched and allow some to be changed as desired.
We had a case where an advanced user found the option to set manual checkout from/to Teamcenter, He then set that option for himself and his colleagues, the colleagues didn't really understand the change, and one of them lost half a days work due to that he couldn't save his assembly. Somebody else had checked out and saved the same assembly. we then locked everything on Site level as the default and unlocks option by option on demand.
