I'm having a problem with a WSS 3.0 instance where users keep losing their upload access rights every night.
Users can always enter the Site involved and can browse lists, document libraries etc. just like normal, but they get an error when trying to upload documents, getting access denied error. This can be fixed by applying their access rights again in WSS, but it has to be done every morning, making that solution not feasible.
This is a dedicated virtual server and no other applications running on it.
Has anyone had a similar problem regarding WSS and Sharepoint access rights ?
