It may be useful to supply an Ethereal recoding of the data on the network when the problem takes place. Perhaps the point at which the board 'dies' can be seen and also the activity that it was performing at the time.
A web page providing links to other files on different servers should not be involved in the subsequent data exchanges and so shouldn't have any problems. However it may not be working exactly as expected and the network activity may show why not.
Regards
