We had a power cut today in the office. Initially you think woohooo, I can relax and have a cup of tea for the 30 minutes and then you realise you can’t make a cup of tea because the power is down.
Then you realise the only work you can do is documentation, AHGHGHGHGG
The power cut happened whilst I was at lunch having a walk, I initially thought it was either some kind of alien invasion or a particular efficient burglar because at least 6 houses had their house alarms going off.
After an hour the power came back up but the company CRM was still down and when I tried to open CRM I was getting a rather nasty error, mentioning Priv User group and a lot of active directory messages.
This was unusual,
I check the CRM server, fine
I checked the Async services, fine
SQL Database, MSCRM_CONFIG, org database, fine
So all the obvious stuff seemed to be ok.
I then looked at the error message and noticed the localSystemAdGuid was a blank guid of all zero’s.
I was speaking out loud, mentioning active directory errors and then one of the developers said try rebooting the CRM server because if it had come up before the Domain controller then the it would affect CRM because it needs active directory.
so I rebooted the CRM server and this resolved the problem.
So there we go, tuck that piece of information and I hope it doesn’t happen to you.
