ASPNET / IIS / MOSS Installation

We have .NET Framework 2.0 and 3.0 installed on our 2003 SP1 servers.
Running aspnet_regiis -lk from the 2.0 subdirectory displays 1.1.4322.0 as
valid (root) and 2.0.50727.0 as valid. Aspnet_regiis -lv displays....

W3SVC/ 1.1.4322.2407
W3SVC/111/Root/ 2.0.50727.0
W3SVC/111/Root/_layouts/images/ 1.1.4322.2407
W3SVC/111/Root/_layouts/inc 1.1.4322.2407

Should I run the aspnet_regiis -i to update the valid root to v2.0 globally
or run the command to do each web site individually? Do I even need to run
any command at all? Thanks in advance for any assistance.
