vcenter 5.1 upgrade: some headaches and surprises

vcenter 5.1: SSO database setup

i’ve been reading over the docs for upgrading to vcenter 5.1 the only gotcha i’ve come across is the manual setting up of the SSO (single sign-on) database and users. you would only do this if you were using a database other than sql express (which i imagine everyone does, at least in production). anyways, […]

active directory: running adprep.exe

i’ve personally only had to go through the adprep process once in 2009 (so far). i figured it would be good to notate the process for future reference though. it came up again recently for a different AD domain… for introducing a windows 2008 DC: run the following from the windows 2008 install media on […]

exchange: temporarily prevent a user from sending email

dell poweredge r510 + powervault md1200 das

to hook up a md1200 DAS to a r510 a PERC h800 adapter card is required. initially, we were shipped a h810 adapter card which happened to be a low-profile pcie card and thus would not fit correctly in the r510 (which requires standard sized cards) the md1200 is connected via mini-SAS cables and the […]

vmware-authd continuous restarting; can’t rejoin host to vcenter

we experienced this issue in 2010, but i never got around to fully documenting the cause and solution. after a planned ESX host reboot, the host would not reconnect to vcenter (no matter how much time went by). /var/log/messages shows: Sep 22 10:26:05 esx14 xinetd[3078]: START: vmware-authd pid=25229 from=127.0.0.1 Sep 22 10:26:05 esx14 xinetd[3078]: EXIT: vmware-authd status=255 […]

windows terminal server: generating new self-signed cert

i seem to forget how to do this every time i need to actually do it… if you have an expired cert on a windows terminal server then restarting the “Terminal Services Configuration” service should auto-generate a new cert. opening up a remote Certificates MMC should allow you to export the newly generated Remote Desktop […]
