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?

Can you do me a favour - clear the counters on that interface then run a sh int each day for the next couple of days? This will show how much is appearing each day or whether it all happens on a particular day etc.

Runts are small packets (less than 64Bytes as i recall) that justy get dropped but they DO indicate a network problem. Use something like Net Monitor or Ethereal/Wireshark - both free - on the ISA Server and watch the traffic from there. Is the ISA nic set to 100Mb full duplex to match the Cisco or set to auto?

I have cleared the counter time 16:00,  I will clear them tomorrow again after I capture in the sh int..  The NIC was set to auto but I changed it to 100.  That  jumped  the speed from  0.16mb/s to 2 mb/s  I wll put etheral on the ISA box.  To see what is going on.

Again thanks Keith.

Okay back, the problem turn out to be setting the correct speed on the nic card on the ISA server.  It was set to Auto but when I changed it to full 100 everything seem to work okay.  Thanks for your help.
