Unable to check out or check in parts
This evening, when several students tried to check out files from our Windchill server, the check out failed (and check in) and this error message came up in the Event Management console: "WTRuntimeException: ATTENTION:
(wt.access.accessResource/19)
Also, when I go to Open and Windchill Commonspace, nothing shows up in the folder; but when I access it from the Folder Browser, I can see all the files.
There have been no changes to the security settings, etc. by anyone on our team. Any idea what could be causing this and how to fix it?
