several LAN Devices are not partially seen trough windows

[lukasroeder]

to control several instruments (powersupply, nwa, dmm), we have a second lan-card in our testsystem control computer. sometimes after the start of our testsoftware, several lan devices are not seen through windows (win7). the viOpen fails, and you even not able to ping the device. the arp-entries are ok. the problem can be solved by flushing the arp-cache via cmd line argument "arp -d". the problem with deleting the arp-cache is that de running user is not a admin, so this cant be automated by the testsoftware

any guys here with the same problem ?

Seems to me that this is a Windows/Networking/Security issue.  Talk with your local IT support gurus.

why do you think it is an IT / Security problem ?

[Bob_Schor]

If it is a networking/protocol/Ethernet/TCP issue, the IT "network" and "security" gurus are usually the most knowledgable about your particular network and what rules and protocols it enforces.  I don't, myself, have an answer for you, but these are the folks I go to here when I have this kind of issue.
