Today, log in to the server, found that since the SQL-SP3 patch did not create a hacker attack success. After the patch is hit, the server's network and dial-up connection cannot be opened, but there is no problem in network access, but it is impossible to modify through the Window interface, and there is no problem with the Netsh command. I found that every time the network and dialing will generate an error (The Server {BA126AD1-2166-11D1-BA126AD1-2166-11D1-B1D0-00805FC1270E} DID NOT Register with DCOM WITHIN THE REQUIRED TIMEOUT.) Analysis may be a DCOM execution error. Check the DCOM service via GUID to the Network Connection Manager Class, AppID is {27AF75ED-20D9-11D1-B1CE-00805FC1270E}, then find the localservice = Netman by appid, Netman This service has been problematic. I have determined what is wrong with the problem. I will find the serviceDLL item in the parameters parameter by finding the registry // hklm / system / service / Netman item, and the DCOM is called to other DLL files, turn this item back to% systemroot% / system32 / netman. DLL and then restart the server. Local connections have finally appeared.
