Ryan,

thanks for your input.  Do I have to do anything to get things working again after the DS is down, or does this happen automatically?  I read in the Advanced Concepts Guide the following:

<snip>
All servers in the farm query the data store when they are started. The following registry setting determines whether or not IMA requires a connection to the data
store to start:
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA\Runtime\PSRequired (DWORD)
Value: 0 or 1
If the value is 0, IMA can start without a connection to the data store. If the value is 1, IMA requires a connection to the data store to start. After the first time the IMA
Service starts successfully, the value is set to 0.
</snip>

Maybe I should set this value to 0 manually to get clients to be able to connect?

You should be able to connect using the local host cache of the Citrix

But interesting.

Subject: [THIN] No connections when DS down

Hi,

Something I don't get: when the Data Store is down, no client seems to 
be able to connect to a Citrix server.  I thought that the grace period 
for datastore non-availability made sure that people could still connect

to a Citrix server, while the DS was being 'troubleshooted'.  Am I right

on this?  I checked that the Data Collector was running (it runs on a 
different machine than the datastore) so IMHO technically clients should

be able to connect??

Erik
