inetpp.dll question? (Software conflict?)

Hi all,
Wondering if someone can shed some light on this issue.
We are running Windows 7ProSP1_x64, and iPrint 5.90 on OES11SP1. We have the iPrint client installed on the clients.
We also run LanSchool (Classroom Management, Monitoring, and Corporate Training Software | LanSchool), classroom management software.

After a few months of trying to diagnose a connectivity issue, I believe I may have found a problem.

In the Client Registry, I see this:
HKLM\System\CurrentControlSet\Control\Print\Providers\Internet Print Provider
Name = "inetpp.dll"

When I install iPrint client (nipp.exe), this value is changed to
Name = "inetpp.dll.INACTIVE"
and a new key is created
HKLM\System\CurrentControlSet\Control\Print\Providers\Novell iPrint Services\...

Now, when I boot, I see an error in the Event log each time, about how the "Print Spooler failed to load print provider inetpp.dll.INACTIVE"
This has been happening for as long as I can remember, and while it's probably deadweight slowing down the boot time, it hasn't affected me.

Now, after much trial and error, I have isolated iPrint and the above "HKLM\System\CurrentControlSet\Control\Print\Providers\Internet Print Provider\.." registry entry as a possible cause of the problem.
When I rename Name to inetpp.dll, or if I delete the entire "HKLM\System\CurrentControlSet\Control\Print\Providers\Internet Print Provider" key, Lanschool begins to work. When I revert the registry and reboot, the problem arises again.

I am about to contact LanSchool for comment, but my question is, is there a reason iPrint installation renames this key? I can only assume it is so an iPrint Client uninstall (nipp-u.exe) can rename it back to original pre-iPrint state (I have verified this is what happens).

Can anyone comment on the impact of changes around this registry key?

inetpp.dll is a Microsoft Windows System DLL. It belongs to the MS Internet Printing Provider.
Novell replaces this with the Novell IPP Provider and renames the registry entry to inetpp.INACTIVE rather than deleting the registry entry.
So if your Software depends on the MS Internet Printing Provider you should check out if iprint still works fine even if you reactivate the ms ipp again.
Otherwise, if your Software works also fine after deleting the MS Internet Print Provider key, I would suggest to do this.
