I've encountered this strange error situation and would appreciate any attempts to shed light on the issue. I've got a squid service running on Windows Server 2003 (this squid service has been running since October 2008) and just the other day (after a power cut) the service will no longer start. The error number when trying to start the service is 1067. The error in squid.exe.log is: 2011/05/25 13:12:28| parseConfigFile: squid.conf:1 unrecognized: 'ï'" (There is a tall rectangle character in those quotes). The last successful and the first unsuccessful entries from cache.log are: 2011/05/22 22:00:02| Starting Squid Cache version 2.7.STABLE4 for i686-pc-winnt... 2011/05/22 22:00:02| Running as Squid Windows System Service on Windows Server 2003 2011/05/22 22:00:02| Service command line is: 2011/05/22 22:00:02| Process ID 3004 2011/05/22 22:00:02| With 2048 file descriptors available 2011/05/22 22:00:02| With 2048 CRT stdio descriptors available 2011/05/22 22:00:02| Windows sockets initialized 2011/05/22 22:00:02| Using select for the IO loop 2011/05/22 22:00:02| Performing DNS Tests... 2011/05/22 22:00:02| Successful DNS name lookup tests... 2011/05/22 22:00:02| DNS Socket created at 0.0.0.0, port 52505, FD 5 2011/05/22 22:00:02| Adding nameserver 10.131.208.10 from squid.conf 2011/05/22 22:00:02| Adding nameserver 10.131.208.1 from squid.conf 2011/05/22 22:00:02| Adding nameserver 208.67.222.222 from squid.conf 2011/05/22 22:00:02| Adding nameserver 208.67.220.220 from squid.conf 2011/05/22 22:00:02| User-Agent logging is disabled. 2011/05/22 22:00:02| Referer logging is disabled. 2011/05/22 22:00:02| logfileOpen: opening log c:/squid/var/logs/access.log 2011/05/22 22:00:02| Unlinkd pipe opened on FD 8 2011/05/22 22:00:02| Swap maxSize 262144 + 16384 KB, estimated 0 objects 2011/05/22 22:00:02| Target number of buckets: 1071 2011/05/22 22:00:02| Using 8192 Store buckets 2011/05/22 22:00:02| Max Mem size: 16384 KB 2011/05/22 22:00:02| Max Swap size: 262144 KB 2011/05/22 22:00:02| Local cache digest enabled;

FATAL: Cannot open HTCP Socket Squid Cache (Version 2.7.STABLE4): Terminated abnormally. I've tried reverting to an earlier config file, building a new config file, forcing encoding to ANSI, tried different line endings. I've tried uninstalling and reinstalling the service. I've tried replacing the squid directory. I've tried replacing and rebuilding the cache directory (it also kicks up an error about that character on the first line of the conf file). I've tried disabling socket pooling for IIS. Anything else I should try?
