  3. Hello,

    Thank you for using newsgroup!

    From your post, I agree with Bob's suggestions. You may first check the
    default time-out period for the autodisconnect feature of the Server
    service, open a command prompt, type the following line, and then press
    ENTER
    net config server /autodisconnect:number

    Please refer to:
    297684: Mapped Drive Connection to Network Share May Be Lost
    http://support.microsoft.com/kb/297684/en-us

    And then please confirm if you have installed any Symantec software on the
    server and clients. As I know, some Symantec could cause these similar
    issues as below:
    932463: A mapped network drive appears to be disconnected after you install
    or upgrade to Symantec AntiVirus 10.0 or to Symantec Client Security 3.0 on
    a Windows Server 2003-based computer or on a Windows XP-based computer
    http://support.microsoft.com/kb/932463/en-us

    More Info:

    330519: Red 'X' appears on Home folder mapped drive in Windows Explorer

    thanks guys, the default autodisconnect is 15 minutes. none of the
    suggestions mentioned apply here. no symantec installed, no compaq programs
    running and no x appears in front of drives. we have 2 DHCP servers
    allocating IPs, and for no apparent reason when users log in in the morning,
    they have no mapped drives, and the only way to fix this is to release and
    renew the IP address.
    thanks

  7. Hello,

    From your reply, you have two DHCP servers in the network. Is this single
    sub-network? Why have you two DHCP servers? Based on my knowledge, some IP
    conflict or assignment issue may be caused by two DHCP servers.

    Thanks & Regards,

    Ken Zhao

    hi we are running a class B network, and the 2 DHCPs are issuing two
    different scopes. ie: 10.0.100.1 to 10.0.100.254, and the other 10.0.101.1 to
    10.0.101.254. all part of the same domain

    thanks

  9. Hello,

    From your description, does the issue occur on all DHCP clients? You have
    to release and renew IP to resolve the issue every time?

    If so, I think this could be related to the network environment. I suggest
    you check DHCP server configuration to see if they are working fine.

    Thanks & Regards,

    Ken Zhao

    it does not occur on all DHCP clients, only about 20%, and yes we have to
    release and renew IP to resolve the issue every time

    i have checked DHCP and it is working fine. the other thing, clients only
    lose their connection to the network shares, but carry on using outlook and
    the internet, so they must have a valid IP address.

  11. Hello,

    I suggest you use "NET USE * /d /y" command to delete all the existence
    mapped drives. And then recreate the mapped drives to see if they will be
    lost.

    If the problem persists, please let us know what OS the client and the
    server are. Have you enabled mapped drives through a script?

    If you used a script to enable mapped drives, we may enable "Always wait
    for the network at computer startup and logon" and "Run logon scripts
    synchronously" on the GPO and try mapping the network drive from a script
    that runs from Startup folder.

    | | it does not occur on all DHCP clients, only about 20%, and yes we have
    to
    | | release and renew IP to resolve the issue every time
    | |
    | | i have checked DHCP and it is working fine. the other thing, clients
    only
    | | lose their connection to the network shares, but carry on using outlook
    | and
    | | the internet, so they must have a valid IP address.
