The IT Crownd

Just doing some patching this weekend and came across this error on one of our servers. windows update error 8024402c No much help on the web - that worked for me so I checked out the windowsupdate.log The update failed to find our WSUS server. So I checked if I could ping the server.  I couldn't. This was due to the DNS suffixes being incorrect. I fixed that and now updates are working! Hope this helps :)

We have a script which runs IE when a user logs in. On our RDS servers we found that users were seeing two instances of IE opening. This is caused by the User Group Policy loopback processing mode being enabled. We need this mode enabled for various reasons so just turning this off wouldn't help.

Whilst this is pretty much a straight cut-n-paste job I have made some changes and kept the more relevant (at least to me) data whilst removing columns I thought we not adding "value".   I added a feature to look up a file called: C:\Scripts\HealthCheck\MailboxServers.csv which is a key/value pair of Mailbox name and mailbox Server name.  This will show you if a mailbox has failed over from the designated mailbox server.   For example, if database1 and database2 are running on my_mbx_server1 and database3 is running on my_mbx_server2 then:  my_mbx_server1, database1 my_mbx_server1, database2 my_mbx_server2, database3 The code will read this file in and check that all mailboxes are running on the designated mailbox servers, if not, the cell is highlighted in red with some text detailing where the mailbox has moved from. Probably th...
