I can confirm this as well, I changed this setting at a site that had been 
experiencing slow browsing and the problem went away completely.

An easier way to apply this setting, by the way, is to use an Active Directory 
Group Policy Object (GPO) and set the

Computer Configuration
  Windows Settings
    Security Setttings
      Local Policies
        Security Options
          Digitally sign client communications (when possible)

setting to "Disabled". This affects the same registry entry, but can be done at 
a domain-wide level to affect all computers in the domain easily. That's what I 
did and it worked a charm. Thanks for the tip David!
