TV Client to Server Connection very slow (2 Viewers)

[azimek]

When starting TV on client ( TV Server is anoter PC) it takes very long for the client to get the channels from database.

2009-01-06 19:56:00.151199 [Info.][Config Main]: ChannelNavigator::Reload()
2009-01-06 19:56:00.238108 [Info.][Config Main]: get channels from database
2009-01-06 19:56:42.787142 [Info.][Config Main]: found:62 tv channels
2009-01-06 19:56:42.789095 [Info.][Config Main]: TvNotify:OnNotifiesChanged

As you see it takes about 40 seconds. This happens when clicking plugins in the tv client configuration or starting tv the first time in tv client.
Client an Server are RC 4. Using SQL Server Express latest ServicePack.

Any suggestions?

Thanx André

Check you have a static ip on the server.

 

[azimek]

All IPs on the Network are static using HOSTs File.
Connection only works fast when starting a MP client on the server.
By the way - all PCs are Vista SP1 systems and LAN 1GB (3 Com)

All logs (tv server and client) don't show any errors that have to do with the connection.
When viewing the connections in MS SQl Server Manager, it shows that the clients connect using "Named Pipes"
SQL Server is configured to accept TCP and Named Pipes connections.

Thanx André

Found a solution but still problems with gentle.config

Problems seem to come from the was MP connects to SQL Server Express 2005 SP2.
Ist I Use : Network Library=dbnmpntw
in the connection string - forcing Named Pipes connection everything works fine.
Tested this behaviour in my own little proggy.

Now I want to implement this new parameter in the gentle.config file but MP configuration overwrites the changes every time i use the MP configuration tool.
So where ist the connection string placed originally????

Fill working connectionstring:
Data Source=Mediaserver\SQLEXPRESS;Initial Catalog=MpTvDbRC4;User ID=sa;Password=MediaPortal;Network Library=dbnmpntw;Persist Security Info=true;

Please help !

Thanx André
