hi, i have windows server 2003 r2 sp1 and i recently received 2 bsod's on my server, 1 around 430 pm and the 2nd around 8 the next morning. the eventlog reported both times: Error code 00000022, parameter1 001400f9, parameter2 f78f69b8, parameter3 f78f66b4, parameter4 8081df7c. I referred to a previous thread about this and am wondering if anyone may have more information on this error 1003. the server was working fine until now. recent changes were increasing disk allocations, revdrive for back up (now uninstalled), acronis backup s/w for servers. i looked into the minidump file and saw that symantec was a frequent word used in there. i hope this is enough information to use. any help would be appreciated.
