Publish PRTG through ISA server 2006



I'm trying to publish PRTGMON through ISA 2006 in order to make PRTGMON APP to work with my PRTGMON server. But whatever i try almost everytime i get an 1790 The network logon failed error. Anyone dealed with this before ?

I have configured my PRTGMON with HTTPS and our wilcard certificate. Browsing from an desktop works like a charm.


Frank Andringa - happy user though :P

I managed to solve this issue. There seems to be an issue where an ISA web publishing rule is configured to work with an SSL connection from an client to ISA and an SSL connection from ISA to the prtg webserver. Normally with IIS webservices on the webserver adding the same wildcard certificate as on ISA solves the problem. But not within this scenario.

I reconfigured PRTG to HTTP and changed the publishing rule accordingly. So Sys Admins are now connecting with SSL to the ISA box and from the ISA box all traffic is redirected to HTTP.

Tip: On ISA you will need to clear out some checkmarks on the http filter which is bound to the web publishing rule

Thx in advance

I also had issues publishing PRTG Network Monitor though ISA Server.

I have recently written up a web-post with a different solution/workaround if you are interested:


Hope this helps!
