Shares Changed Drive Letter of the Shared Folder after a Reboot on Windows 2003

-

hi,

i have file server running windows server 2003 standard edition patches upto 5/30/12. server connected storage array via scsi , has 8
folders being shared. drive letter volume "s:\". folder called "xyz" shared folder "s:\xyz"

we have volume has drive letter "t:\" attached via local storage. we conducted a dr test, took full backup of "s:\" , restored "t:\" using netbackup. test successful , restore. had "s:\" , "t:\" have identical data except "s:\" production , has shares on it. never rebooted server our test , data stayed on 24 days no issues.

on june 1st rebooted server part of our monthly maintenance , after reboot shares hosted on "s:\" drive changed drive letter "t:\" "xyz" folder went "s:\xyz" "t:\xyz". the shares security , permissions intact so when users accessed shared folder, date was24 days old.

the correlation find reboot couldn’t find else change drive letter. checked on array , looked healthy , there no errors reported nor there errors scsi cards or system hardware.

can provide me guidance why drive letter change occurred. if need additional info please let me know. thanks



so found root cause why drive letter got changed. when used netbackup restore t drive used existing backup set of s. in simpler terms, took full backup of s drive , restored data onto t drive. netbackup preserves security , shares of files , folders. netbackup before backup checks , gets aware of folder structure , shares these folders have. when did restore shares put backup because told netbackup preserve settings. going thru backup logs saw warning messages tells, "the 'server' service needs restarted in order shares take affect." since never rebooted server, normal should server waiting on pending "server" service restarted move shares over. once reboot done shares on t drive went in affect. change drive letter.

i have pc has power settings pushed out default domain policy in ad environment. of course on local machine "some settings managed system adminstrator". the machine temporarily no longer in contact domain controller (it's been physically moved , not on same network now) can't updated gpo settings. i believe if edit local group policy won't make difference because of group policy processing , precedence. since it's temporary away ad network, still want use settings of ad user. is there somewhere in registry stored can edit power plan manually until can sync domain? (i need prevent sleeping while plugged in - it's set 1 hour) thanks! allen crist i found site: http://gpsearch.azurewebsites.net/#7916 i able add policy to hkey_local_machine\software\policies\microsoft\power using specs found on site. looks solved issue. i'll report if didn't. thanks! allen crist ...
