Hotline Client

You can disable Hotline 1.55 Client banner by modifying or adding "hosts" file of TCP/IP.

1. Make or add (if already exist)  a file named "Hosts" with simple text in System Folder with

banner.hlserver.com A 127.0.0.1
banner1.hlserver.com A 127.0.0.1
banner2.hlserver.com A 127.0.0.1
banner3.hlserver.com A 127.0.0.1
banner4.hlserver.com A 127.0.0.1
communitybanner.hlserver.com A 127.0.0.1

2.  Open TCP/IP control pannel and do Edit --> User Mode. Then click "Advanced"

3. Click "Select Hosts file..." button and select the "Hosts" file. 

That's it!

By doing this the Hotline Client can not find the address of banner server. 

 BTW, if you want to make the banner space of Toolbar small, open Hotline Client 1.55 with Res Edit. 
Open "GIF" and change 3C00 to 0100 in second row.
