I have arcserve 2000 workgroup edition (build1018) on a windows nt 4 server sp6 and my backup says that it is successfull, all engines are working no nt errors but in the job summary i have the error stating that "failed to login to database engine" EC-2005. i can restore via backup media but not by session, this is blank. I now have .cat files in my arcserve/temp directory. I have checked the security account and that doesnt seem to be the problem , i think its a corrupt database but how do i fix it, i have a bunch of files such as dbcheck.exe,dbclean.exe, in my arcserve folder but i'm just looking for insight before i try running these applications. thanks again for any help
