I am receiving a rpc server unavailable 800706ba error when trying to connect to a remote PC.
Firewalls are turned off on both machines. The remote machine is running Windows 7 Pro.
the strange thing is if I go into Explorer and map a drive with the identical user name and password below, it will map fine. i then disconnect the mapped drive and re-run the code below, and it works. however, if i reboot the machine, it will give me the same error message. i then go back into Explorer and repeat the process and it works fine.
any ideas as to why? I would greatly appreciate any help.
i use the following code:
ConnectionOptions options = new ConnectionOptions();
options.Username = "userName";
options.Password = "password";
string adsiPath = string.Format(@"\\" + IP + @"\root\cimv2");
ManagementScope scope = new ManagementScope(adsiPath, options);
scope.Connect(); // this is where it raises the error
ObjectQuery oQuery = new ObjectQuery("SELECT * FROM Win32_Service WHERE name = 'serviceName");
using (ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(scope, oQuery))
updateStatus("Found " + oSearcher.Get().Count + " instance(s) of the old sync service.");
