I am running dnn 5.02.03 on a Windows Server 2003 and suddenly all the links in the HTML modules quit working for anyone that is not a host or admin.  I checked all page and module permissions and did not find anything incorrect or for that matter different from the previous day.  Can someone help me identify the relationship between the dnn link (specifically the tabid in the linkclick.asp? string) and the filename.  Not knowing what to do I did try to resync (using File Manger) but because the host can pull up the link target and the link address is the same for users and host that should have little to do with the problem.  I appears it must be a permissions problem.  What I am trying to do is determine which tables are associated with the process and from there I figure I should be able to determine at which point the permissions come into play and therefore determine the problem and caused.  Thanks in advance.

Thanks again, that seem to correct the problem.  Looks like we had someone that thought that area had to do with the page permissions.  Live and learn I guess.
