|
* - Reappeared in 1.9.16p11 with fixed smbd services
|
|
* Version 4.20 - To indicate that nmbd and browsing now works better
|
|
* Version 4.50 - Set at release of samba-2.2.0 by JHT
|
|
*
|
|
* Note: In the presence of NT4.X do not set above 4.9
|
|
* Setting this above 4.9 can have undesired side-effects.
|
|
* This may change again in Samba-3.0 after further testing. JHT
|
|
*
|
|
* Version 6.1 - For older smb server versions, MMC doesn't let offline
|
|
* settings to be configured during share creation. Changing
|
|
* it to 6.1 to mimic Win2K8R2.
