Revit Architecture 2013 . I can see servers but not connect.

Hello,

 

We've just finished installing Revit Server 2013. Revit Admin comes up fine, along with listing a couple of project folders we manually copied into place. We've got the RSN.ini files in place and when we go to open a project we can see the server listed. If we click on the server to connect it pauses for a bit then a pop-up says "This operation could not be completed. Please try again. (contact administrator etc)"

 

I've gone through and opened up ports 80 and 808 on the router's firewall, the Win2k8R2 firewall, the workstation's Win 7 firewall, and even added connection rules to Symantec Endpoint Protection which also handles all the firewall policies on the network. I've tried using Netmon and Procmon to see what incoming/outgoing ports Revit is using.

 

Netmon:

 

- All Traffic   - My Traffic    - Revit.exe (1676)     - IPv4 (192.168.1.70 - 192.168.1.96) ConvID = 3        TCP (52960 - 808) ConvID = 4        TCP (52962 - 808) ConvID = 22        TCP (52963 - 808) ConvID = 57        TCP (52964 - 808) ConvID = 66

 

Procmon:

(domain name changed in log for security)

 

10:32:37.6386877 PM Revit.exe 1676 TCP Reconnect workstation.internal_network.local:53587 -> revsrv.internal_network.local:808 SUCCESS Length: 0, seqnum: 0, connid: 0 10:32:43.6388828 PM Revit.exe 1676 TCP Reconnect workstation.internal_network.local:53587 -> revsrv.internal_network.local:808 SUCCESS Length: 0, seqnum: 0, connid: 0 10:32:58.6426212 PM Revit.exe 1676 TCP Reconnect workstation.internal_network.local:53588 -> revsrv.internal_network.local:808 SUCCESS Length: 0, seqnum: 0, connid: 0 10:33:04.6428966 PM Revit.exe 1676 TCP Reconnect workstation.internal_network.local:53588 -> revsrv.internal_network.local:808 SUCCESS Length: 0, seqnum: 0, connid: 0

 

 

Does Revit Server need to be on my router's DMZ? Are there possibly any other ports, protocols, policy objects or permissions that I am overlooking here? Any help would be appreciated.

 

Thanks in advance.

Putting Revit Server in the router's DMZ would be a good test to see if security on the router is causing the issue.

 

Revit Server uses ports 80 and 808 for communication, but it also has pre-requisites (such as File and Printer Sharing) which can utilize other ports. I've found it is easiest to setup Revit Server with everything open, and once it is working, start locking things down and re-test.

 

Some other issues to be aware of:

-       The workstation needs to be able to communicate directly with the host server (and accelerator when applicable) as well as the reverse.

-       The system names need to be consistent between the LAN and WAN (e.g. the name used to access the host server/workstation/accelerator has to be the same for every system).

-       The IP addresses need to be consistent between the LAN and WAN.

-       The IP address needs to resolve to the system name and vice versa. If I ping the server name, and get its IP address, and then I resolve the server name from the IP address (using ping -a), I should get the same name I started with.

Hi Lance,

 

I would like to ask for clarification around what you said:

"The workstation needs to be able to communicate directly with the host server (and accelerator when applicable) as well as the reverse."

 

  1. If the Revit client is communicating through the Accelerator, should there be any communication between client and Host?
  2. From my perspectve, it's been noted that even though the client is communicating through the Accelerator, on the Host its TCP ports 80 and 808 need to be open. Why would this be the case if data should be flowing through the Accelerator?

There is practically no documentation by Autodesk (that I've ever seen) on the technical aspects of how the communication flows between servers and clients.

 

Thanks.

This information applies to 2013 and later versions of Revit server:

 

The reason that the workstation needs to be able to communicate directly with the host server, is because communication from the workstation goes to both the accelerator and the host (not just the accelerator).

 

The accelerator provides model data (which is large), but the active permissions data (which is normally smaller) is stored on (and retrieved from) the host server directly.

 

More information on this is in the following video (at about the 6 minute mark):

Video: Revit Server - What it Does and How it Works

 

Additionally, if the accelerator stops responding/functioning, the workstation will automatically fail over to communicate entirely with the host server. This will cause reduced performance for certain operations, but users can continue to work.
