Recently installed a new WSUS server, the system is Windows 2019, as an old driver. It's not easy to install a WSUS, but there are times when old drivers turn over. After installing the wsus, it will not be able to start, and a lot of errors have been reported:

Error log 1: the source Windows Server Update Services event ID 7053WSUS management console encountered an unexpected error. This may be a temporary error; try restarting the administrative console. If this error persists, try deleting the permanent preferences for the console by deleting the wsus file under% appdata%\ Microsoft\ MMC\. System.NullReferenceException-the object reference is not set to an instance of the object.

After searching, I found the same buddy:

Just change the memory limit of the application pool to more than 4G:

Find the IIS manager, open the application pool, find WsusPool, click Advanced Settings on the right, and change 1843200 to 4096000 in the dedicated memory limit item, that is, from 1.8G to 4G. Of course, if you have enough memory, you can change it to 0, that is, unlimited.

But I couldn't do it after I did it. After that, no matter how much you search, you can't find a second solution. Opening the default httpd://ip:8530 with a browser will indicate a 503 error. If you think about it, there is still something wrong with iis, and you have to solve the problem of iis. Come on, look for items one by one, and finally find a limit on the number of connections, just cancel it, and the problem is solved.
