Hi Joe, We are prohibited from using Microsoft AD Users accounts and computers to create accounts and I do not wish to violate any policy. Fortunately the group has put in bug fix to our developers to correct this issue. It's not a big deal, I am was just trying confirm that this was not a Microsoft limitation in 2003 AD that I was not aware of. Thank you so much for your help and Chucks as well as everyone on the list. Jose :-). ----- Original Message ----- From: joe To: ActiveDir@xxxxxxxxxxxxxxxxxx Sent: Friday, June 16, 2006 9:21 AM Subject: RE: [ActiveDir] NETBIOS Character Limitation? The $ for computer accounts isn't included in the NetBIOS name for nameres, only in the DB and that was to hide them from being displayed with normal user accounts in NT days. What is the web based tool? Tell the vendor to fix it. In the meanwhile, create the account another way. -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm From: ActiveDir-owner@xxxxxxxxxxxxxxxxxx [mailto:ActiveDir-owner@xxxxxxxxxxxxxxxxxx] On Behalf Of Medeiros, JoseSent: Friday, June 16, 2006 12:06 PMTo: ActiveDir@xxxxxxxxxxxxxxxxxxSubject: RE: [ActiveDir] NETBIOS Character Limitation? Greetings, I am trying to create a 15 character SQL cluster node name in Active Directory using a web based tool. The tool will only allow me to use 14 characters and the Active Directory group states ? The 14 character limit is due to the '$' that must be appended to the samAccountName for backward compatibility. WINS has a 15 character limit. To ensure there is always room for the '$' the field is limited to 14 characters ?. I have been working with WINS since NT 3.51, and NetBIOS has always been 15 characters followed by a 16th binary value. The last 16th binary value is for a unique ID. I have Michael Masterson's WINS & DNS book (I was on the board of the NTEA www.ntea.net with him ). http://www.amazon.com/gp/product/1562059432/qid=1150472910/sr=1-7/ref=sr_1_7/002-3567057-9128019?s=books&v=glance&n=283155 Was the character limitation of 15 reduced in AD 2003 and Wins and is it now 14?
