very slow connection from a WIN95 PC

-- Hi, I have a INFORMIX ONLINE-Server 7.22 installed on a Windows-NT-Server. I have a problem with the connection from a WIN95-PC to the Database-Server. I have installed Informix-administrator-tools and client connect 2.50. When i start the the database-explorer on my WIN95 Client, it takes 3 to 5 minutes to show the databases in the explorer. When i click on a database, it takes 5 minutes to show the tabels. On the NT-Server, the database-explorer works very fast. I cant't find a problem in the network, hostfile, services are ok. Name-resolution via host-file are o.k. A ping to the NT-Server answers under 10 ms. Setnet32-entries are correct. What can I do? Torsten AChatz
