I appreciate any help ! W32Time? I have 2 PDC in Active directory one of them got the backdoor virus, which effected the W32Time.exe. To clean the virus, Symantec suggested to delete the file, so I did, and I downloaded one from the net on the Winnt\system32. As I did that the server was so slow, the processor %100 most of the time- it was up for 10 min- then I stopped the service " Windows Time " and the server is back and running, but most of my Windows 98 & XO &2000 they can not synchronize the domain time, and some time you can browse the network, and most of the time you can't, and network resources is out too. I have the error message from the computers and the server! my question is; any one know how to configure the win time on 2000 server using W32Time?
