 421 /* This was set by JHT in liaison with Jeremy Allison early 1997
 422  * History:
 423  * Version 4.0 - never made public
 424  * Version 4.10 - New to 1.9.16p2, lost in space 1.9.16p3 to 1.9.16p9
 425  *              - Reappeared in 1.9.16p11 with fixed smbd services
 426  * Version 4.20 - To indicate that nmbd and browsing now works better
 427  * Version 4.50 - Set at release of samba-2.2.0 by JHT
 428  *
 429  *  Note: In the presence of NT4.X do not set above 4.9
 430  *        Setting this above 4.9 can have undesired side-effects.
 431  *        This may change again in Samba-3.0 after further testing. JHT
 432  *
 433  * Version 6.1 - For older smb server versions, MMC doesn't let offline
 434  *               settings to be configured during share creation. Changing
 435  *               it to 6.1 to mimic Win2K8R2.
