Which version is that new client? I'm wondering if would affect in any way, clients working on a company owned OCS environment. Regards Diego R.

Apparently the new LiveMeeting client requires access to port 8057. Microsoft's original explanation was that the LM client first tried port 8057 and if that was unavailable it would fall back to port 443. I could see this happen, in fact. But as far as I can tell, the newer client would then fail anyway if it couldn't use 8057. Once I allowed traffic over that port, all went well.

But I've been doing a lot of back-and-forth with our LiveMeeting team. And they have an open case with Microsoft's LiveMeeting support folks. What we've figured out so far is that there are no problems with an older version of the client (which I have on my computer at work). Using that client I can upload anything I want, including the same PowerPoint that out LiveMeeting team members can't upload. The newest client (which is on the computers of our LiveMeeting team, as well as the computers of most of our clients) has the problem described-inability to upload PowerPoints, with the error I described below. Size (of the PP) doesn't seem to matter. Interestingly, other file types CAN be uploaded, no problem. When I get into work later this morning, I'm planning to upgrade to the latest client on my work computer and see the problem replicated. I will post more results later this morning. But if anyone has any insight now, it will be gladly accepted!

As far as I know, return traffic takes the same path as the original traffic. All of our traffic comes in and out through the ISA server. There were some preceding errors. I'll try to duplicate those and let you know what they were. I'll also try to find out if any other kind of file can be uploaded.

As I understand it, however, the FWX_E_TCP_NOT_SYN_PACKET_DROPPED is something you see commonly with stateful inspection on the ISA Server; indeed, this error code is generally indicative of packets being dropped because of stateful inspection; this traffic didn't match any conversation currently in the ISA Server's state tables. That being said, a possible cause of this is an asymmetric route between your client and the destination. Do your internal clients use the ISA Server as their default gateway or another router? Is the return traffic to the client taking the same path into of your environment as the original client traffic took leaving it? For example, if you assume the ISA Server is used the default gateway by the internal clients, the traffic flow of an asymmetric route might look at follows: Client -> ISA Server -> Router -> LiveMeeting -> Router -> Client. That may not be the cause, though, as there are still other questions to consider. Are the users able to upload any files at all? Is it just the PowerPoint files that can't be uploaded? Are there any status error or warning codes that preceed this one? If so, what are they? Try taking a network trace and looking at that. That might ultimately be what you need to do to determine the root cause.

(Getting ready to go to TMG, not there yet.) Users on my network suddenly can no longer upload PowerPoints to their Live Meetings. If they use their computer elsewhere (home or whatever) and are NOT connected to my VPN, then they can upload them just fine. I did some monitoring on one of these failures and here's the result: Original Client IP Client Agent Authenticated Client Service Server Name Referring Server Destination Host Name Transport MIME Type Object Source Source Proxy Destination Proxy Bidirectional Client Host Name Filter Information Network Interface Raw IP Header Raw Payload GMT Log Time Source Port Processing Time Bytes Sent Bytes Received HTTP Status Code Cache Information Log Record Type Authentication Server Log Time Destination IP Destination Port Protocol Action Rule Client IP Client Username Source Network Destination Network HTTP Method URL Result Code Error Information 172.17.201.34 PHL-ISA3 - TCP - - 2/1/2010 7:28:42 PM 31707 0 0 0 0x0 Firewall - 2/1/2010 2:28:42 PM 65.221.5.36 443 HTTPS Denied Connection 172.17.201.34 Internal External - - 0xc0040017 FWX_E_TCP_NOT_SYN_PACKET_DROPPED 0x0 I feel fairly certain that this error has been queried to the list before (maybe not with Power Points being uploaded into Live Meetings), but I couldn't find any answers in the archive.
