Is there a chance that this is related to my ExCM instance? That's the only forms based authentication I have in place on this prticular server. Thanks!

    I'm going to guess this error occurs when the FBA login cookie expires. If so, this is a natural event is should not be cause for alarm. If your cookie expiration length is long, say 2 weeks, it may be that most users login on Monday but when they try back 2 Mondays later their cookie is expired. Unfortunately login/cookie management is a SharePoint feature and not part of ExCM. I would recommend opening a support ticket with Microsoft if your users are experiencing issues. If I find out more I'll pass it along.

    Thanks Jeremy. I do have a couple of users that are having problems uploading documents where it seems that their attempt to upload coincides with one of these events in the Event Viewer.

    I was able to log in with a test account I have and had no problems uploading using a couple of different steps, check out forced, versioning on and off etc... Users on the other hand are getting that wonderful "Unknown Error" when they try and upload the same file. I directed them to delete their temp files and cookies and see if that makes any difference. Time will tell.

     Thanks again for your reply. I appreciate it!

    In some cases you can get a better error message by turning off SharePoint's friendly error message feature. Learn how to do it here....

    http://help.sharepointsolutions.com/products/excm/webframe.html?Troubleshooting_General.html

     In addition, if editing documents is your issue Microsoft released an Office Client update which makes Client Integration (Office Integration with SharePoint) possible in an FBA environment. Typically Client Integration is turned off in an Extranet. You might want to have your clients install the patch and enable Client Integration (Central Administration -> Application Management -> Authentication providers -> Zone). You can read more here...
