Distributed Sniffer 4.3.5 Sniffview connection problems

[damage2]

I'm currently having problems in connecting Windows XP or Win 2000 PC with sniffview to a Distributed sniffer 4.3.5.

I have the agent up and running and can use the webConsole which works OK, however, if I use Sniffview to connect to the agent basically it times out and I get a message

"This instance is halted waiting for a critical resource to be available"

I have tried this from a XP and Win 2000 client and experance the same issue. Basics like IP connectivity are OK I said can use a brouser to access the webconsole

Any ideas of how to kick this into life ???

This probably isn't your problem, but it's worth asking. I had a similar problem with XP and sniffview 4.3 till I realized that my desktop firewall was blocking connections from the DSS (I want to say it was TCP 135).

Some pointers that might help;

- It could be possible that your network is not forwarding a fragmented packet, which I think can cause this.

- Could be a firewall issue, check if port 2001 is blocked..

- Novell Client installed on the agent? This can cause problems.

Cheers guys,

Problem now resolved, AZeemeri was closest to the actual issue.

The network is a basically a L2/3 ethernet LAN and the issue ended up as a code bug on the access switches, where for some reason it was blocking some of the Sniffview traffic. No ACLs etc were configured. It would pass other traffic OK like ping, telnet, FTP etc but impacted the Sniffview client/server stuff. This problem was only evident on the gig ports of the particular switch and OK on other models of switch from the same well known manufacture. Code upgrade on the switch sorted the problem, so didn't spend any more time looking at what was actually happening.

Could you give some particulars?

Which switch model? Which code versions?

We may be having similar issues and not know it.
