AS/400 share not accessible with Windows 7

Microsoft Windows 7
At a moment we cannot map a AS/400 share on  WIndows 7 machine anymore after restoring a image with MDT2010. We tried to connect with \ipnumbershare and with \sharename. Tried it on several Windows 7 machines which were deployed. Tried several (not locked) user accounts, but every time the message appears on the W7 system: cannot locate connection: network error. All other mappings are good but the share to the as400 cannot be made anymore.
Searching the internet may come to: local policy - security - lanmanager ltm setting but tried several settings but none works.
What can cause this in Windows 7 that the connection to the AS400 share cannot be made anymore?
Is one setting responsible that the connection cannot be made?
Important maybe: the mapping is made after the error but when choosing the mapping no connection is made and the error appears again..
The image is changed (it is a virtual image made with VMware but making the share after deployment was never a problem now suddenly it is...
Somebody has some tips?

Thanks. We'll let you know when a new response is added.

I have installed wireshark to monitor the traffic. after the image is deployed the connection mapping to AS400 share can be made. The system must be restarted however, after restart i never can access the mapping again.

So i captured the netwerk connection with wireshark before restart and after restart. Then i try to compare the results to the destination (the as4000 share) that is the traffic in WIreshare but don”t see much differences no errors…

    You may need to install a network analyzer and monitor the traffic between these two hosts to see what's happening. That should tell you everything.

    What is your AS/400 OS release? What is the OS on some other systems in the same network that have working shares? -- Tom

    Other machines have also the same WIndows 7 Pro clients. The AS400 OS release i don''t know, must go after that..

    Windows Networking can change with some releases of Windows. AS/400 OS releases generally match Windows Networking protocols according to the Windows versions that Microsoft was releasing at that time. Knowing the AS/400 OS version can help us to know what protocol versions should be expected.

    For both Windows and the AS/400, there can be patches that would be applied in order to help synch up the way one or the other talks to other systems.

    If you have other systems in your network that are successfully exporting shares, it could help us know what is needed for the AS/400 to provide similar service.

    The WRKLICINF command should show a version number of the OS on one of the first detail lines in the License Term column.

    Hi,

     

    I can see there V6R1M0

    The W7 systems are the same image so there is no differences in versions.

    Though no difference in the W7 systems, do you have any Windows Server systems (or Unix/Linux) that are exporting shares for your users? If so are those shares visible? And in general, do any of the W7 systems export successful shares? Are any successful shares exported from anything? -- Tom

    I don't exactly know what you mean by exporting shares but if you mean that the W7 systems can map shares yes all of the shares except the AS400 share.

    We tried to connect with \ipnumbershare and with \sharename.

    Are you actually using just a single back-slash? Or do you enter "\\ipnumbershare" or "\\sharename", i.e., with two leading back-slashes?

    No sorry of course not, we use: \\ipnumber\sharename but this is not the problem.

    No problem. I had to ask. If you simply use "\\ipnumber" without referencing any named share, does any useful result happen?

    Do all users log onto their local machines rather than using a networked logon?

    Has anyone verified that the NetServer server function is running on your AS/400? And if it is, is it defined with the same network domain name that the W7 systems are configured for? (Or the same 'workgroup' name?)
