I can no longer upload drivers to Iprint broker.
On selecting W2K drivers, add from file error in firefox.
"uploading resources to broker from add form file not currently suppoted.
IE gives nothing bar error on page in status bar.

The server is NW65 SP5
The client is running NW client 4.91 sp2, OS W2k SP4.
Iprint client 4.20
IE ver 6 sp1 and Firefox is 1.5

It has worked prior to upgrade from SP3 to SP5.

Anyone come across similar or have work around.
