WSUS and computers that have been reimaged or are just not showing up.
Posted on 2016-10-18
I have a wsus server that has been running for about 5 years. Many of the computers that report to the server have been reimaged over the years. When the computers are reimaged should I be removing the previous entry for these computers from WSUS or should they just be able to populate the old entry for that computer? It seems that some of the computer just update the previous entry for their host name in wsus and some dont. If I remove them and then send a command to report now it appears they show up in wsus as reporting recently. Also how should I go about troubleshooting computers that do not show up in the WSUS list? They all have the reg entries for wsus update and reporting applied via gp. I confirm this on the computers in question but I do not see some of them in the list. Is it a bad idea to just remove all computers from the wsus list and just have them repopulate the next time they report in?
