Client PC's dropping network connection to SBS 2008. 0x8007054b Error?
Posted on 2009-04-10
I just installed a 2008 SBS for a company. They have 25 users. Their network consists of 1 router and a few switches. They really just use the server to share some folders and 3 printers. We are eventually going to use it for exchange but right now it just shares things. I have AD installed and everyone's workstation is logged in and has the correct drives mapped. This server is running DNS and DHCP services. The DHCP address scope is: 192.168.1.100 - 192.168.1.150. The primary DNS is the server's IP, the secondary DNS is the first DNS server of the ISP we use. The issue we are having is that the one application they use is stored on the server. All that's required on the workstation is a shortcut to the folder with the data files and license information, there is no program to install on the server. All of the users get kicked out of the program between 1-3 times a day, at random. I don't see anything in the event logs of the server that would explain this but I do see this in the workstation logs:
"Automatic certificate enrollment for local system failed to contact the active directory (0x8007054b). The specified domain either dose not exist or could not be contacted.
Enrollment will not be performed."
What does this mean? Shortly after that error, it kicks them out. I also get this error:
"Windows cannot access the file \\myserver\ProgramFolder\ProgramFile.exe for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing."
Nothing in the network equipment has changed, just that I switched their old computer with this server. Any ideas? Someone suggested that it could have something to do with the time settings on the server/workstations? Any help would be GREATLY appreciated. =D
