I had installed one my VM with Win 2008, gave a long name, bumped up with DC and added DNS,Web roles. Dropped SQL 2008 and MOSS 2007 all went well. When I tried to Install K2 BlackPerl, the Configuration Manager kept on failing to successfully configure.
Then I noticed that the error message that K2 BlackPerl Configuration Manager log that the server could not be found!!!!!
The log complained this against the SQL Server and Web Server .
Here is the name of my server from Machine Properties:
Here is the name of my Server:
The Name of SQL Server:
Notice that the Win2008DevBoxx64 (4 is missing from the Server name in the Server Manager and SQL Server above)
Then I went back to K2 BlackPerl Configuration Manager, correct the name (Win2008DevBoxx6) and deleted the extra character(s) at the end as seen in the SQL Server/Web Server, everything went well.
Then my research lead to this reference on TechNet:
Active Directory Maximum Limits – Scalability (http://technet.microsoft.com/en-us/library/cc756101(WS.10).aspx)
Under the section “Additional Name Length Limitations"
NetBIOS computer and domain names are limited to 15 characters.
