Unable to open mapped folders in IFS

[scott.r@manches]

Either unable to open or very slow to open my IFS folders on my Iseries (AS400) via windows explorer
I have mapped my IFS which is all fine, but sometimes and lately it appears to have got quite bad.
I can?t open any folders in the IFS.
I see the mapped drive fine, then click on it and see all the folders in the IFS, then if I click on a folder in the IFS the cursor wheel spins with message of no response, then I get an error saying ?the specified network name is no longer available?. But they are there, sometimes after this message I can go in to the folder and work on files fine.
I have checked in the security policy editor on my PC and the settings are
?Send LM & NTLM - use NTLMv2 session security if negotiated?
I have checked in the service webclient and it is setup to start automatically.
I have tried a different windows browser called CubicExplorer, this is just the same.
There must be some sort of a conflict or sharing error, as sometimes I can click in to the folders and files straight away, sometimes it takes 5-10 minutes, then once I get the error message I can get in after that.
I?m running Version 7.1 on my Iseries
Any help would be great.

Re: Unable to open mapped folders in IFS

Hard to say, but in this situation I would advices getting IBM support involved. They may need to look at communications data between the server and your client.

If this is happening across the board there is a good chance it's network related and not client/server related.

The only thing I can think of to check that could maybe contribute is verifying that the IBM i NIC and network switch ports where it is plugged into the network are all set to 1GB/full duplex (or whatever the best option is in your situation). If either side is set to auto-negotiate it can cause problems especially with IFS-related functionality.
