I just updated from ISA 2004 to ISA 2006. The install went okay but now I am noticing my upload speed has drop by 1/10. I have disable all filters on the ISA box but have the same problem.
When I check the interface on the Cisco 2811 I see errors coming from the ISA server. When I bypass the ISA server, the speeds are normal.
Download speed is okay.
Currently running 10 Mbps from my ISP.
Any idea on what can be causing this?
