Hi

 First check ip settings of Server,run "ipconfig /all" and paste here we can check.And also make sure you can able to Access this server.

On a client ping the server,then run on cmd "telnet serverip 3389"

Configure Network Level Authentication

1. Click Start, click Run, type regedit, and then press ENTER.
2. In the navigation pane, locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. In the details pane, right-click Security Packages, and then click Modify.
4. In the Value data box, type tspkg. Leave any data that is specific to other SSPs, and then click OK.
5. In the navigation pane, locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders
6. In the details pane, right-click SecurityProviders, and then click Modify.
7. In the Value data box, type credssp.dll. Leave any data that is specific to other SSPs, and then click OK.

This worked for me.

SecurityProviders key got missed in my registry, created and added "credssp.dll" as value and worked. Thanks.
