I found that the properties of File and printer sharing for Microsoft Networks service disabled after I install the windows server 2008 64bits. I tried to install that service via adding the file and printer sharing services in the properties of local area connection, but it doesn't contain any service in the popup box. Also, no such service file available in the disk when I tried to install the service from installation disk of windows server 2008 64bits. Is the file "sacsrv.dll" corresponding to the service name of file and printer sharing? I found it is in the directory of "Windows\system32". I have no idea about where is the problem? Do I miss some components? Please tell me what can I do for it? Thanks!
