ibm midrange - IBM iSeries COnnection String Issue -

I am using .NET IBM iSeries library. This is the connection string that I am using:

  & lt; Connection add string = "datasource = myserver; userID = xxxx; password = xxx; connection timeout = 60; allow unsupported room = true" name = "myConnection" />  

It works on a laptop and not on the other.

I have a "connection string invalid"

for anyone reading this You can trace iDB2InvalidConnectionStringException and to see how the system takes a crime to see the "MessageDetails" property.

In my case, this connection does not like the "AllowUnsupportedChar = true" attribute on the string because (as Charles has probably given above) I get access to I Access for Windows I am using v6 , R1 worked on other machines where we have installed v7 .
