>  When running IBM LAN Server 4.0 Advanced with IBM LAN Distance Connection Server you may experience 
>  problems with insufficient NETBIOS resources.  Two possible symptoms indicate this problem: 
> 
>  o When starting LAN Distance error message WCL554 appears stating that the LAN Distance product requires more 
>    NETBIOS resources than are available. 
> 
>  o The NETBIOS protocol does not load at system startup. 
>  
>  If either of these symptoms occur, the following steps are recommended: 
> 
>  NOTE:  Restart your workstation after each step to see if the problem is solved. If the problem remains, try the 
>  next step. 
> 
>   1. Remove any unnecessary NETBIOS applications. 
> 
>   2. Edit the \IBMLAN\IBMLAN.INI file.

>      In the [Network] section, reduce the number of NCBs.  See example below:
