    OSD import permission Issue

    We might get when we are looking for only import permissions for a user or Group..

    or

    even when we setup the permissions at the end of the wizard we may get this error..

    Errors

    ·You do not have security rights to perform this operation.

    ·ConfigMgr Error Object:

    ·instance of SMS_ExtendedStatus

    ·{

    · Description = “User \”*************\” does not have permission of the current site to import machines.”;

    · ErrorCode = 1112017920;

    · File = “e:\\nts_sms_fre\\sms\\siteserver\\sdk_provider\\smsprov\\sspsite.cpp”;

    · Line = 766;

    · ObjectInfo = “524288″;

    · Operation = “ExecMethod”;

    · ParameterInfo = “SMS_Site”;

    · ProviderName = “WinMgmt”;

    · StatusCode = 2147749889;

    };

     

    The actual permissions required at SCCM Console level is:

    1. On SCCM Root Collections we must grant read & read Resource
    2. and for the target of the collection we need to give the permissions to add or whatever you wanted
    3. at computer Association level we must give permissions for importing
    4. (The most common mistake or un- mentioned step ..this one we may forget most of the time)

    On the top of the Site ==Properties=> Security Tab => Class Security rights and we must choose here read,Import Computer Entry (below screenshot)

    To get ride of IIS Webdav issue

    Most of the time some or other application extension would be blocked because of IIS Webdav Settings issue, to stop filtering in IIS Webdav we can change the

    setting at the site level, i.e., open inetmgr/ IIS Console and chose the server name and in the right side we need to choose the “WebDav Authoring Rules” and in actions you will see “WebDAV  settings” click on the  button and you need to configure you Request filtering Behavior as below.

    PXE error: PXE-T01:File not Found & PXE-E3B: TFTP Error – File Not Found

     

    You might get the below error..

     

    image

     

    The above problem will come When you don’t Have the files in DriveLetter:\RemoteInstall\SMSBoot\  

    In fact the below article address the issue, However I have approached in different way as just copy the Missing files & folders from other Remote Install Folder and past on the Problem system.

    AD computer Numbers vs SCCM Computer Numbers

    read here more http://smsug.ca/blogs/garth_jones/archive/2008/12/03/how-to-add-ad-data-to-configmgr-reporting.aspx

    AD it just another database, just like SQL server is. With that in mind there is nothing stopping you from using SQL to link to AD to give you data about your AD environment!

    1) Create Linked Server using SSMS

    exec master.dbo.sp_addlinkedserver 'ADSI', 'Active Directory Service Interfaces', 'ADSDSOObject', '<DC Name FQDN>'

    2) Modify the security for ADSI using SSMS

    exec master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N'ADSI', @locallogin = NULL , @useself = N'False', @rmtuser = N'<Domian>\<User Id>', @rmtpassword = N'<Password>'

    3) The hard part is over!

    4) Create query to query AD and ConfigMgr

    This query will list all PCs within AD that are NOT within ConfigMgr (or SMS)

    select

    AD.cn as 'PC Name(AD)',

    AD.operatingSystem as 'OS (AD)',

    AD.operatingSystemServicePack as 'SP (AD)'

    from

    openquery (ADSI,

    'SELECT cn,

    operatingSystem,

    operatingSystemServicePack

    FROM ''LDAP://<DC Name FQDN>''

    WHERE objectCategory = ''Computer''') as AD

    Where

    AD.cn not in (Select name0 from v_GS_Computer_System as CS)

    order by

    AD.cn,

    AD.operatingSystem,

    AD.operatingSystemServicePack

    This query will give you a count of all OS that are NOT within ConfigMgr (or SMS)

    select

    AD.operatingSystem as 'OS (AD)',

    count(AD.operatingSystem)

    from

    openquery (ADSI,

    'SELECT cn,

    operatingSystem,

    operatingSystemServicePack

    FROM ''LDAP://gartek-dc.gartek.tst''

    WHERE objectCategory = ''Computer''') as AD

    Where

    AD.cn not in (Select name0 from v_GS_Computer_System as CS)

    Group by

    AD.operatingSystem

    order by

    AD.operatingSystem

    So what does this report look like.

    image

    So there you have it.

    Solution: Remove the Client authentication and SMS certificates Certificates of from Certificates console and request new certificates

    PXE-T00: Unspecified file opening error detected

    Found the error: While deploying 7 with the SCCM 2007 and MDT 2010.

    Solution:This is not related to SCCM / WDS Issue.. it was with Symantec Ghost caused the issue, once the service was stopped the issue is resolved.

    How to change the SCCM Client Log files size to Max value that you want

    Sometimes or other we might need to retain the max size of log files for reading/analyzing.

    Here are some useful info………… in this regards………….

    Client side reference registry

    For X86 systems

    -          HKLM\Software\Microsoft\CCM\Logging\@GLOBAL

    For X64 systems

    -          HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\CCM\Logging\@GLOBAL

     

    The reference key is Log Maxsize

    I tried to change manually by regedit how it is showing error as can’t be edited the value..

    So I depended on below WMI script

    ' VBScript to change the Log File Size on a ConfigMgr client

    ' Change the 500000 to your required size in bytes

     

    Dim newLogMaxSize

    Dim sMachine

    newLogMaxSize = 500000

    sMachine = "."

    set oCCMNamespace = GetObject("winmgmts://" & sMachine & "/root/ccm")

    Set oInstance = oCCMNamespace.Get("SMS_Client")

    set oParams = oInstance.Methods_("SetGlobalLoggingConfiguration").inParameters.SpawnInstance_()

    oParams.LogMaxSize = newLogMaxSize

    oCCMNamespace.ExecMethod "SMS_Client", "SetGlobalLoggingConfiguration", oParams

    ' End of script

     

    So Do not change the registry value directly!

     

    The SDK shows the SetGlobalLoggingConfiguration Method in Class SMS_Client

    How to learn / Education

    Education has five aspects

    1. Information -- Often we think information is education, but it is only one aspect of education.

    2. Concepts -- Concepts are the basis for all research. You need to conceive in order to create.

    3. Attitude -- An integral aspect of education is cultivating the right attitude. Proper attitude at the right time and place determines your actions and behavior.

    4. Imagination -- Imagination is essential for creativity, for the arts. But if you get stuck in imagination, you may become psychotic.

    5. Freedom -- Freedom is your very nature. Only with freedom, do joy, generosity and other human values blossom. Without freedom, attitudes become stifling, concepts become a burden, information is of no value and imagination becomes stagnant.
     
    Just understand these five aspects of education.
