Hi, I am having a problem, I have installed ISA 2k on Windows 2k3 (Fully updated with Sp2) when ever there is an electricity breakdown my cache crashes and in Alert section i received Alert messages "Cache container initialization error" "Cache restoration completed" "Cache container recovery complete" "Configuration error". These errors are in Alert and in Event logger this message i receive: Event Type: Error Event Source: Microsoft Web Proxy Event Category: None Event ID: 14176 Date: 10/10/2004 Time: 7:30:28 AM User: N/A Computer: SERVER Description: Disk cache D:\urlcache\dir1.cdat failed to initialize. Some errors were encountered when ISA Server restored specific data cache files. ISA Server will now attempt to recover these files. These errors may have occurred because there was not enough time to complete all necessary shutdown operations, when ISA Server was previously shut down. To avoid this in future, you can increase the value of the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\WaitToKillServiceTimeout registry key. Identify the reason for cache failure by examining previous recorded events, or the error code. The error code in the Data area of the event properties indicates the cause of the failure (internal code: 503.6333.3.0.1200.365). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. Data: 0000: 5c 06 00 00 \... That Key in registry i think will increase time to terminate that service but here it is electricity failure, what should i do I have reinstalled my windows also but the error still continues, and i think this is 1st time i am having problem such like that, and an other interesting thing, ISA only Caches 5000 URLs, when PC is running it reaches even on 18000 URLs, but after restart or Shutdown it again reach back to 5000. This problem has started when i bought 40 GB hard drive, Previously i have 20 GB Hard drive and on that cache was working fine. Waiting for your responce Mashahood Ahmed
