SCOM Agent Install Issue: Failure of operating system version verification.

I was trying to install SCOM  2012 R2 agent from the console on a couple of our remote DR servers, However we received the following error message every time we tried the install. "The operations manager server cannot process the install/uninstall request for computer. Failure of operating system version verification." As checked RDP  and  Ping worked fine, There was no firewall issue as it was disabled. Permissions for Agent account were correct. However when we tried to access the \\server\C$ it failed. It turned out WAN optimization  software was blocking CIFS access As soon as we made changes to allow CIFS access , SCOM agent installation worked fine. Hope this helps.

Netscaler AGEE plugin and Windows 8.1

I recently tried to access VPN site (Netscaler SSLVPN ) from Windows 8.1 laptop However i could not connect to the resources . After checking the logs , i found that the AGEE client version on the laptop was not correct as it did not match the server version we had (10.125.8) I downloaded the AGEE version specific to our Netscaler Environment (10.125.9) in our case. After installing this version of AGEE and restarting the laptop , i was then able to connect to the VPN resources. Hope this helps.

Find all active domain Users in a particular OU

Sometime s you need to find AD users in a particular OU who have logged on to any system  in past 90 days . I found this powershell query online that helped me to create a html report for all users with the logon times. $oldDate = (Get-Date).AddDays(-90).ToFileTime().toString() Get-ADUser -SearchBase 'OU=Users,dc=domain,dc=com' -Properties lastlogontimestamp -LDAPFilter "(lastlogontimestamp>=$oldDate)" |     select @{n='User';e={$_.name}}, @{n='LastLogOn';e={[datetime]::FromFileTime($_.lastlogontimestamp)}} |     ConvertTo-Html -Title 'Recent Users' | Out-File 'RecentUsers.html' Invoke-Item 'RecentUsers.html' Hope this helps.
