I have add a couple of new client workstations to our network and used the add new computers wizard to discover them. They have appeared in the All Computers group but not in the All Clients group. I found an older thread here which suggested using the properties page for the All Clients group and use Explicit Members to add them. That option is disabled on our system, is there another way to do this?mike...

Hello Mike,With my experience, you cannnot modify the properties of All Clients group because it is a built-in and protected group of SCE server. Please navigate to Overrides tab of All Clients Properties page,click Overrides... -> For all objectsof type: All Clients. What is the value of Override Setting column? Is there a tick on Override column? Clear the tick to make sure the Discovery Rule works.Besides, please check the event log of Operations Manager. Is there any error message logged? Thanks,Yog Li - MSFT

Thank you for your response Yog Li,I checked the Override setting by clicking on the Override... button and selecting All objects of type: All clients. The check box is clear. I also checked the OPMAN log on the server and saw no errors that looked like they were related to the client PCs in question. I checked the OPMAN log on one of the clients and saw no errors, there were several Event ID 2120 warnings that the Health Service had deleted 1 or more items which could not be sent in 1440 minutes.mike...

Hello Mike,Please delete all Network Devices from Administration space -> Device Management -> Networked Devices and reinstall agents to see if the issue resolved.It seem like a bug of the SCE Network Device MP. If you are using SCE RTM version, please upgrade it to SCE SP1. And then download and install the latest version of Network Device Monitoring Library MP from the link below:Microsoft System Center Network Device Monitoring Management Pack for System Center Essentials 2007 SP1 (KB960569)http://www.microsoft.com/downloads/details.aspx?FamilyID=8200e405-f871-4f19-a991-0411285fcbe5&displaylang=enThanks, Yog Li - MSFT

Hi Yog Li,I finally got time to try your suggestion and deleted the entries in the Networked Devices space. That seems to have been a partial fix, 3 of the 5 client workstations are now appearing in both All Computers and All Clients. I still have two which have not appeared yet.Is it possible that they may appear as SCE re-scans the network?mike...

Hi Mike,How about the two agents now? If they are still not appear, pleace check ifit related SusClientId. Run "regedit.exe" on every problematic machine, and find it under "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate". If the values of the SusClientId are identical, you can delete the SusClientId manually on every machine. To do this, stick the following lines in a batch file and run it on all clients. And it should get fixed.net stop wuauservREG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v AccountDomainSid /fREG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v PingID /fREG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /fnet start wuauservwuauclt /resetauthorization /detectnow Hope it helps.Yog Li - MSFT

I think I'm okay on this now. I still have one workstation which has not appeared, but it belongs to one of our owners and has not been turned on since I deleted the network devices. I do not have access to it but I'm sure it will pop up the next time it is powered on. If it doesn't I will try your batch file.I think we can consider this one solved at this point. I have added one new workstation since my last post and it appeared in the "All Clients" group right away.Thank you for your assistance with this. This has been an example of how a forum like this can be a wonderful asset.mike...mike...
