then i will select the server from the shard list, and this procedes..
client disconnected from 127.0.0.1 ( 0 connection )

then shortly afer the client says "Client cannot attach to the server. it must have been taken down. Please try again in a few moments. :?

[02/09 22:06:10] Client#2 connected from 127.0.0.1 (1 connections) on interface 127.0.0.1
Account marvin19491 logged in from 127.0.0.1
[02/09 22:06:13] gethostbyname("poldev") failed for server POL-ip
[02/09 22:06:19] Client#2 (127.0.0.1): disconnected (account marvin19491)

check servers.cfg in the config file make sure thats pointing to the right address

Both your servers.cfg in POL and the login.cfg in your UO folder must match in order to log into your server.
