Please post more details so we can understand this issue more clearly.<br/><br/>The &quot;Installation in Progress&quot; pending management type indicates that the agent was installed, but has never successfully connected to the management server. In this state, the Approve command is unavailable by design (because it's a push install) and the only options are to reject the agent or fix the communication problem. General connectivity problems can cause this, however the most likely cause is a Kerberos error.<br/><br/>Please read the article below for more information and solution:<br/><br/>OpsMgr 2007: Agents stuck in Pending Management with Event ID 21016<br/><a href="http://blogs.technet.com/smsandmom/archive/2008/03/13/opsmgr-2007-agents-stuck-in-pending-management-with-event-id-21016.aspx"><span style="color:#0033cc">http://blogs.technet.com/smsandmom/archive/2008/03/13/opsmgr-2007-agents-stuck-in-pending-management-with-event-id-21016.aspx</span></a><br/><br/>Hope it helps,<hr class="sig">Yog Li - MSFTMon, 29 Jun 2009 12:10:41 Z2009-06-29T12:10:41Zhttp://social.technet.microsoft.com/Forums/en-US/systemcenter/thread/3abf8f8a-3796-4440-b7aa-150b7f3d95e6#dd2dffb3-c0bd-405d-8ebe-e4338820ebc1http://social.technet.microsoft.com/Forums/en-US/systemcenter/thread/3abf8f8a-3796-4440-b7aa-150b7f3d95e6#dd2dffb3-c0bd-405d-8ebe-e4338820ebc1Naztahttp://social.technet.microsoft.com/Profile/en-US/?user=NaztaMost clients appear in BDD - but not yet contacted and health status shows ErrorHi,<br/><br/>I have actually managed to resolve the issue - well half of it anyway - I got rid of the &quot;installation in progress&quot; error by removing a couple of Duplicate SPN's<br/><br/>So Agents are found and showing in &quot;Managed agents&quot; but when I check the computers pane the computers show &quot;computer has not been contacted yet&quot;<br/><br/>the re-install was just wiping the SCE server clean and re-building it from scratch - computers are bieng added to the AD SCE mananaged computers group.<br/><br/>The computers can ping the SCE server - the registry entries for the WSUS/SCe are correct on client and I have followed all the troubleshooting in this blog but no luck<br/><br/><a href="http://blogs.technet.com/operationsmgr/archive/2009/04/23/sce-2007-computers-and-agents-showing-as-not-yet-contacted.aspx">http://blogs.technet.com/operationsmgr/archive/2009/04/23/sce-2007-computers-and-agents-showing-as-not-yet-contacted.aspx</a><br/><br/>thanks for you assistanceMon, 29 Jun 2009 13:11:29 Z2009-06-29T13:11:29Zhttp://social.technet.microsoft.com/Forums/en-US/systemcenter/thread/3abf8f8a-3796-4440-b7aa-150b7f3d95e6#1a4dc15b-482b-4361-a487-276e5b15bf6dhttp://social.technet.microsoft.com/Forums/en-US/systemcenter/thread/3abf8f8a-3796-4440-b7aa-150b7f3d95e6#1a4dc15b-482b-4361-a487-276e5b15bf6dYog Li - MSFThttp://social.technet.microsoft.com/Profile/en-US/?user=Yog%20Li%20-%20MSFTMost clients appear in BDD - but not yet contacted and health status shows ErrorHi Nazta,<br/><br/>Gald to hear the &quot;Installation in Progress&quot; pending problem resolved.<br/><br/>Some general netwok problems can cause &quot;not yet contacted&quot; issue.
