Windows Update 971657 killing me softly. -----Original Message----- From: Ziots, Edward [mailto:[email protected]] Sent: Thursday, July 22, 2010 11:11 AM To: NT System Admin Issues Subject: RE: Net Use requires password
This was the complete issue with the DCOM for me, I posted on earlier: Happened with RDP in my case. Problem: * TCPIP NetBIOS helper service and Win32 time service * When doing an RDP we were getting an "RPC server is unavailable." Cause: DCOM Permissions were modified Resolution: 1. Imported Winsock2 and Winsock from a different machine and applied 2. Updated Netbt.sys to latest, KB961799 5.2.3790.4452 3. Disabled SNP. 4. Disabled Non-Microsoft services using msconfig 5. Set the Dcom permissions: I. Open up the "Component Services" MMC. II. Click on the Start Menu, then select "Programs" and then "Administrative Tools" and click on "Component Services". III. Then Expand "Component Services", and then "Computers", IV. Highlight "My Computer" then right click and select "Properties" V. Click on the "COM Security" tab. VI. Click on the "Edit Limits" button, under "Access Permissions" VII. Click on the Add Button, and add "Everyone" with "Local Access" and "Remote Access" VIII. Click the OK button. IX. Click on the "Edit Limits" button, under "Launch and Activation Permissions" X. Click the OK button. XI. Click on the Add Button, and add "Everyone" with "Local Launch" and "Local Activation" Results: * We went to services and started the TCPIP NetBIOS helper service and win32 time service * We were able to RDP to the server.
