    Been having this problem for a while. Only noticed it since deploying printers with Group Policy.

    Redirection, Mapped / Network Drives and Printers (all must require a persistent connection) are being dropped randomly. At first we thought it was when the machien went to sleep, however we extended sleep timer to 2hours (to cover lunch time) and the issue still occuring (some people even get it in the first 10mins of the day!).

    Went through the MS Technet and was informed of the Network Cards sleeping (changed the reg settings site wide) and made no difference.

    So does it annoy any of your users enough for them to be a trail blazer and have sp1 installed? It would be good to know if it fixes it, or whether I need to live in fear of it happening here!

    Bursar had the issue a couple of days back.

    We are set up as follows -

    Windows 7 Clients
    Hyper-V Server Environment
    Server 2008R2 Print Server (Virtualised)
    Server 2008R2 hosting Shared Areas (Virtualised)
    Printers and drive maps deployed via Group Policy Preferences
    PaperCut as our Print management software (happened with pCounter as our print management software as well)

    More setup posts might allow us to get a feeling for the cause of the issue?

    Windows 7 clients (pre SP1)
    VMware ESX 4.x environment
    DC server 2008 (virtual)
    File server 2008 R2 (virtual)
    Printserver was 2003 initially, but has since been replaced with 2008R2 machine (virtual)
    Papercut as our print management, though i dont think this really has anything to do with the issue.

    What method are you installing printers on the client machines?

    If you create this reg key it might do the trick:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System
    EnableLinkedConnections = 1 (DWord)


    I used this key for a quite similar problem so perhaps its worth giving it a go.

    Added this as a deployed reg entry to all desktops with the Registry preferences. Hopefully we hear less of the problems.

    "Redirection, Mapped / Network Drives and Printers (all must require a persistent connection) are being dropped randomly. "

    What do you mean by 'dropped randomly'?
    Have you raised a call with Microsoft?
    Have you tried capturing an network trace using netsh in Windows 7?
    Have you tried the advice in this KB Article:Mapped Drive Connection to Network Share May Be Lost?

    While that last article appears to mostly be talking about server side tuning, there is a sentence in there that related to the client side:

    "To change the time-out duration in the client-side during a UNC connection, specify the arbitrary time in KeepConn.
    Locate and then click the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic e\lanmanworkstation\parametersValue: KeepConn
    "

    Finally that article also says:

    "Did this fix the problem?

    * Check whether the problem is fixed. If the problem is fixed, you are finished with this section. If the problem is not fixed, you can contact support (Contact Us)
    ."

    In my experience(*) 'I have the problem outlined in KBnnnnnnn, and it advises me to call you' is the magic incantation to getting non-chargable support from MS PSS.

    (*)3 out of 7 calls

    Opened a thread on Technet forums -

    Group policy printers dissapearing from client machines intermittently

    MS informed me to test with Vista, so i am imaging 2 machines now to attempt to re-create the error.

    Having checked the event logs on the computers that are having this problem i found the following event that is occuring on all machines when the printers are lost.

    Code:
     
    The user 'BURSARY-ColourCopier' preference item in the 'User Policy - Base {E1631A9F-2A31-461C-9FDF-BCD42202FBA4}' Group Policy object did not apply because it failed with error code '0x8007000a The environment is incorrect.' This error was suppressed.
     
    The user 'ACCOUNTS-Laser' preference item in the 'User Policy - Base {E1631A9F-2A31-461C-9FDF-BCD42202FBA4}' Group Policy object did not apply because it failed with error code '0x8007000a The environment is incorrect.' This error was suppressed.
    Anyone else got a similar error?

    The resolution for Printers was the following registry entry (which prevents printers being re-installed with GP refreshes).

    "Do not apply during periodic background processing" needs to be enabled in the following policy.
    [COMPUTER POLICY\ADMINISTRATIVE TEMPLATES\SYSTEM\GROUP POLICY\Printers preference extension policy processing]


    Hope this helps someone out.

    There is also

    "Do not apply during periodic background processing" needs to be enabled in the following policy.
    [COMPUTER POLICY\ADMINISTRATIVE TEMPLATES\SYSTEM\GROUP POLICY\Network Shares preference extension policy processing]


    This should deal with the mapped drives.
