Windows File Protection and Windows

Disabling Windows File Protection

You may disable WFP by setting the value SFCDisable (REG_DWORD) in HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon. By default, SFCDisable is set to 0, which means WFP is active. Setting SFCDisable to 1 will disable WFP. Setting SFCDisable to 2 will disable WFP for the next system restart only (without a prompt to re-enable).

Core Dump Management on the Solaris OS

bash-3.00# coreadm -g /globalcore/core.%f.%p -e global
bash-3.00# coreadm -G all -I all
bash-3.00# coreadm

* Wait for the system/process to core dump
* When system returns:
a. dmesg
b. get a copy of /var/adm/messages and /var/log/syslog
c. get a copy of the system core if a system/kernel panic, from /var/crash and/or the pwd if a process dump
