Programs hang when using files from mapped network drives. RRS feed

  • General discussion

  • I run and use a Windows 7 network for a very small office. 5 computers total, one acting as a server, all running windows 7 professional. A D-link 10/100 unmanaged switch does all the networking, and all computers have Realtek 10/100/1000 adapters.

    We basically run three main programs that use mapped network files; Sage Peachtree(accounting), and Autodesk Inventor(Drafting), and basic MS office programs.

    Peachtree performance is poor at times, fine at times. It seems to "hang" sometimes, especially after even a short time away from the program. Wait times when it "hangs" are anywhere from a few seconds to what seems like MUCH longer than that.

    Inventor problems are very similar, opening, saving, and browsing for files all cause short pauses, and larger compound operations cause significant wait times.

    These problems strangely enough popped up AFTER we upgraded the hardware on our server machine. The new machine has 8gb the ram, a quad core AMD processor, SATA drives, and a 1000Mbps onboard networking. All major improvements over the old hardware, but the network seems slower than ever.

    Our cabling is only cat 5, and I'm under the impression that gigabit Ethernet doesn't work fully on cat5 cable? So a faster switch wouldn't be doing us much good?

    Below is a mostly complete log of things I've tried so far, I've omitted some of the Peachtree specific setting that are needed on all computers running Peachtree.

    Sorry for the lengthy post, I'm just trying to get all this info out there and maybe get some help and help somebody else.

  • Hi,

    Does the issue occur on all the computers? Please check if this helps:

    Files on network shares open slowly, open as read-only, or you receive an error message


    Try to disable third-party antivirus programs or firewall temporarily to check the issue. You can also check in clean boot mode to see if it is caused by software conflicts:
