Full version of WSUS client troubleshooting

Problem:
The client cannot update the patch from the WSUS Server
After you check the related services and the imported registry, you can try the following operations.
 
1-1
1. Use WSUS Client Tools to check the Client
There are three software checks:
WUServer = http: // 10.10.10.5: 8530
------- (WSUS server address)
WUStatusServer = http: // 10.10.10.5: 8530 ----- (WSUS server address)
(1) UseWuServer is enable
--------- Pass
(2) onnection to server
---------- Pass
(3) SelfUpdate folfer is present
---------- Pass
Perform the 2-1 operation if all three items are PASS and the client does not have any patch updates.
For example, if the first two items pass and the error 80072efd is displayed
Solution: Use proxycfg-p proxyservername: port (proxyservername: port WSUS server address and port) on the client)

2-1
1. Stop the Automatic Updates service and BITS service and run:
Net stop wuauserv
Net stop bits
2. Delete the % windir % \ softwaredistribution directory
3. Start the Automatic Updates service and BITS service. When these two services are not started, they will automatically create softwaredistribution and related sub-files.
Run:
Net start wuauserv
Net start bits
4. When the % windir % \ softwaredistribution directory has been created, connect the client to the WSUS server immediately.
Wuauclt.exe/resetauthorization/detectnow
5. After 15 minutes, check whether the client has checked the required updates.
If the problem persists, perform the following operations on the WSUS client:

1. confirm that the Background Intelligent Transfer Service is started.
2. Run the following command to rename the Catroot2 folder.
Net stop cryptsvc
Ren % systemroot % \ system32 \ catroot2 oldcatroot2
Net start cryptsvc

If the preceding operation persists, copy the WindowsUpdate. log file in the windows folder on the system disk for analysis by professionals. (Note: Check that the WSUS server is correct. Other PCs can be updated normally .)
