RM Smartcache keeps falling over.......
The admin logs state:
The caching service exited since authentication responses were not being received quickly enough from the AD and a backlog has been noted several times. The caching service exited unexpectedly. This is likely to result from external issues reported over the preceding 10mins which include 76 authentication exchanges which have suffered from network congestion
However I have pushed out via GPO to our site our old schoolname.proxy.county.sch.uk so the smartcache is currently under very light load....
RM belive we are overloading the smartcache OR that there is a network issue between the smartcache and the DC it's pointing to for NTLM authentication.
I wondered two things...
1. Can I see some figures of number of clients everyone is running successfully through their smartcaches - we have 750 clients but suspect the actual number that are on at any one time and simultaneously accessing the internet will be much lower - though I've been told the smartcache does nt log this - so it's a guess but I would say around perhaps.....300 at any one time?
2. Is there anyway to test the speed/performance of the network between the DC and the smartcache other than a very basic PING command?
