NT4.0 IE 5 Requirements

[Gallerson,Charles,GLENDALE,Information Technology]

Is IE 5 required for TSM BA Client to run properly on NT 4.0 with Service
Pack 6?  Are there any special dll requirements for NT 4.0 for TSM client
5.1 to work properly.  When IE 5 is installed on the client the backup works
if it is not installed it hangs the CPU at 100%
