Remote UI doesn\'t work

[Bayandin]

When I try to start remote UI project it fails.
Log on remote client:

I tryed to add configs [ui]
aliveTimeout = 30
alivePriorityClass = 1
and create new projects, but nothing changed.
WinCC OA 3.14 P001, Windows 7 x64 Pro on both PC's.

Not sure but it might be a DNS problem. Try to add the following config entry on the server in the general section:
noReverseLookup = 1

You should check if all your machines are DNS resolvable - on the server and on the client.

We have slightly the same problem. Cannot connect Client to Server. On client the following massage.

Could this parameter also in this case solve the problem?

[mkoller]

Probably yes. It seems data manager takes too long to respond after the connection has been established, which is a sign that it might be just waiting for DNS to return.
You should check your DNS setup but you can of course try the config entry.

Problem solved after editting hosts file

[shotdunyun]

Thanks for your last posting, I'm experiencing the same problem, though on version 3.12.
Could you share with me how editting the hosts file would work?

[hotze.brons@strukton.com]

In windows in directory C:\\Windows\\System32\\drivers\\etc you will vind the extentionless hosts-file named 'hosts'.

http://www.howtogeek.com/howto/27350/be ... osts-file/

[leoknipp]

how to define the entries in the hosts-file is described in the following part of the WinCC OA help:
Special functions --> Redundant network connections

This chapter is related to redundant network connections, in case of single network connections the entries look similar without the definition of the redundant network.

We do not have DNS.
I am trying to connect over VPN connection.
This means that i will not have always same IP address, so I cannot insert my IP address into HOST.ini file.
Is there any way to solve this problem?

[hotze.brons@strukton.com]

In my opinion a Fixed IP adress is a must in non-office environment.

Fixed IP adress over VPN is possible normaly. Connect your Systemadministrator.
