• How to enable an active/active file server cluster in windows 2008 r2 Enterprise

  - by Phygg

  I've just created a cluster for my file servers in Windows 2008 R2 Ent SP1 environment. The goal - an Active/Active cluster for web server data How do I go about telling the cluster to be active for both nodes? Do I have to tell the cluster to be active/active? Here is a link to the instructions I followed when configuring the failover cluster. http://technet.microsoft.com/en-us/library/ff182326(WS.10).aspx So if anyone can help me to grasp the concept or maybe I'm way off and I need a node that is not active along with 2 active nodes to do this, I would appreciate it.

• How to enable directory browsiing in IIS7?

  - by frankadelic

  How I enable directory browsing in IIS7? MS technet says this can be done in the IIS console: Open IIS Manager and navigate to the level you want to manage. In Features View, double-click Directory Browsing. In the Actions pane, click Enable if the Directory Browsing feature is disabled and you want to enable it. Or, click Disable if the Directory Browsing feature is enabled and you want to disable it. http://technet.microsoft.com/en-us/library/cc731109%28WS.10%29.aspx However, my IIS console doesn't have the Directory Browsing option mentioned in Step 2. How can this option be made available. Note, this is for a static HTML site, so I don't have any web.config or ASPX files.

• All Tasks..Advanced Operations option missing from Certificaces MMC Snap-In

  - by JohnFx

  I am trying to follow the instructions in this article to create a custom certificate to support SSL on a web server. I'm stick on the following step: Click on Personal – All Tasks – Advanced Operations – Create Custom request The problem is that on the web server (Windows Server 2003 R2) I don't have an "Advanced Operations" option under "All Tasks". I do on my desktop machine (Windows 7), but not on the server. All the documentation I can find indicates that it should be available on WS-2003-R2, but it just isn't. Note: I'm going through this manual process because I need to specify a alternate host names in the CSR, which you can't do through the IIS 6.0 console certificate managment functionality. Any suggestions for how to make this option show up?

• Why has ESXi 5.0 not used the software RAID configuration on my test server?

  - by kafka

  I've got a test server which was running WS 2008 Enterprise on the bare metal. It was correctly using the software RAID 1 configuration (2x250 GB disks which appeared as one disk), setup on the Dell Poweredge T110 (which meets compatibility requirements) without requiring any extra setup from me. (As an aside I'm fairly sure it's software RAID, as we didn't spec a hardware RAID controller, if that's of any importance in this situation). I am now testing installing ESXi 5.0 on this server to run some VMs. I've successfully installed ESXi, and imported a VM fine, but it's showing 2 x 250 GB disks available as datastores. However they should be appearing as one volume. When I boot the server, there is a RAID configuration screen you can enter, and I'm guessing this is what I'll have to do at some stage, but now need to be very careful because there is one disk which contains data that I want to be mirrored on the other disk. What is the best thing to do in this situation?

• icacls, Network Service, and setting ACLs on Windows Server 2008

  - by Ted

  Setting ACLs on Windows Server 2008 via the command line is giving me some problems. As per http://web2.minasi.com/forum/topic.asp?TOPIC%5FID=26907 I've tried all sorts of variations: C:\Windows\system32icacls "D:\Websites\site.com\Web\bin*" /grant 'NT A uthority\NETWORK SERVICE: (OI) (CI)M' C:\Windows\system32icacls "D:\Websites\site.com\Web\bin*" /grant "NETWORK SERVICE": (OI) (CI)M And all variations in between. However, each try leads to i.e. "Invalid parameter "'NETWORK'"" depending on the variation above. As per http://technet.microsoft.com/en-us/library/cc753525%28WS.10%29.aspx (see in comments), it appears that others have experienced the same issue where the same command works on Windows 7/Vista/etc., but not on Windows Server 2008. What's the best way to apply permissions to Network Service account on a directory and/or files via the command line in Windows Server 2008? Especially as there's no way to do multiple file permissions at once via the GUI (see http://serverfault.com/questions/30991/windows-server-2008-change-security-settings-for-multiple-files-at-once).

• difference between server and desktop

  - by user1241438

  I want to set up a webserver. I would like to buy a hardware for that and i am trying to understand if i should buy a desktop and host the webserver on that or do i have to buy some used server from ebay and host on it. Example is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180986172861&ssPageName=ADME:X:RTQ:US:1123 But what is the difference in desktop and server? These days even desktops are coming with high RAM. Only other difference i see is servers have RAID HARD disk. Is there any other difference?

• Websphere 7: Getting 'Internal Server Error' when accessing JSPs. Servlets ok

  - by paul

  I have just installed WS 7 on our stage server. The test server was done some months ago. I have deployed the same applications to stage as on test. One application is causing me problems. I call the login servlet but the result is an 'Internal Server Error' message. From my logs I can see that the servlet processed the log in successfully and redirects to a JSP. That is the last message. I can find no further info in any of the other standard out/err logs. I have tried creating a simple JSP containing only HTML - same error. If I rename the file to test.html, it displays correctly. The plugin configuration appears to be identical with the one on the test server (where everything works) Ideas anyone?

• Creating disk snapshots in Windows 7

  - by Puneet Arora

  Does anyone know of a command or tool to create disk snapshots on Windows 7 (client SKU)? I see vssadmin.exe has a "create shadow" option, but that's available only on server SKUs: http://technet.microsoft.com/en-us/library/cc788055(v=ws.10).aspx I've a backup tool that replicates changes (creations, modifications and deletions to files and directories) since last backup, to my backup volume. Before each time this happens I want to create a persistent snapshot on my backup volume. I could then mount previous snapshots to view previous backups achieving a behavior similar to that of TimeMachine in OS X. This question has been asked before but unfortunately there weren't any good answers: Taking snapshots of filesystem/volume in Windows 7?

• How do I setup a syslog server for my network?

  - by Solignis

  I would like to setup a syslog server to forward all log file from all of my VMs and servers. I really don't much about what is out there. So I turn to the community, Something on Linux is fine, what I want more is alert ability like emails telling me something is not right. If there was something to sort the logs by source that would be cool. Where would I want run the syslog server from? My admin WS or a server/VM? Any input would be wonderful. Thanks in advance.

• Spotify stopped scrobbling to libre.fm - unable to login

  - by dsolimano

  I've set Spotify up to scrobble to libre.fm using the hosts file hack, as specified on the wiki, adding these two entries to my hosts file. 149.20.54.250 post.audioscrobbler.com 149.20.54.250 ws.audioscrobbler.com This worked for a while. However, Spotify now tells me that it can't log in to libre.fm. I've double checked my username and password. I haven't changed anything else. Using nslookup confirms that the above names resolve to the correct IPs. So, how do I fix this?

• Time Synch Architecture in Windows Domain Environment

  - by Param

  I just read the following article -- "In a domain, time synchronization takes place when Windows Time Service turns on during system startup and periodically while the system is running." ( http://technet.microsoft.com/en-us/library/cc779145%28v=ws.10%29.aspx ) From the above article i get to know that the first sync it take as soon as i start my system, but after that in how many minutes or second or in how many periodic interval my windows client ( Window XP, window7 or window server 2008 member ) synch with my Domain controller (PDC emulator )??? Do you have any idea, and how should i verify my synch time interval? My Domain Controller is Window server 2008 R2 Standard

• Apache log lines contain "..."

  - by mtah

  We have a custom log line format for Apache logs which are analyzed. CustomLog "|/usr/sbin/rotatelogs -l /mnt/var/log/apache2/access-%Y%m%d%H%M%S.log 900" "%a %{%s}t \"%r\"" However, some log lines are mysteriously shortened with "..." for some reason, but how can this be? The shortest length line discovered where this occurs is 317 chars while the longest line is way over 2000 chars.

• Web map services displaying poorly

  - by user29261

  Web map services no longer display correctly in ArcGIS and Google Earth - no one else on network is experiencing these. Using windows 7 OS. These problem began abruptly (1 day they were working, the next they were not). Specific problems include not displaying at all; correct display on 10% of the monitor and repeating lines of coloured squiggles and text on the remaining 90%; and small, widely spaced, pixels in place of colour fill. Links where this occurs: arcgis http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en Google earth http://openmaps.gov.bc.ca/kml/BCGov_Web_Map_Library.kml I can't pinpoint any changes to the computer setup which may have prompted this, however, adding arcgis 10.1 SP 1 occured around the same time. Probably just a coincidence. Anyone had similar problems? or solutions to these? Thanks for any thoughts. Jim

• HyperV management through Windows 8

  - by Snake

  Consider the following setup: 1 Hypervisor 3 Clients (Server 2012 with AD, Server 2012, Windows 8). Now we can remote desktop into the Hypervisor and manage the VMs with the manager. This also works from the Server 2012 (I installed the manager there). But it doesn't work from the Windows 8 machine. All machines are in the same domain. Am I forgetting something? I followed this long page http://technet.microsoft.com/en-us/library/cc794756(v=ws.10).aspx But I find it so weird that it works for the same user on Windows Server 2012, but not on Windows 8.

• System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse request failed with HTTP status 40

  - by John Galt

  I am trying to make some enhancements to a production web app. After quite a bit of unit testing on my WinXP IIS 5.1 development machine, everything works on my localhost so I used the Visual Studio 2008 PUBLISH dialog on my Dev PC to push the following projects to a staging server: the primary web app the "primary" webservice (the home page tries to invoke this WS) a "secondary" webservice (not yet a problem because home page does not invoke this WS) I get the following when I try to browse to the home page of the web app typing this into my browser: link text Server Error in '/zVersion2' Application. The request failed with HTTP status 404: Not Found. Description: An unhandled exception occurred during the execution of the current web request.Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Net.WebException: The request failed with HTTP status 404: Not Found. Source Error: An unhandled exception was generated during the execution of the current web request.

The staging server is Win Server 2003 ServicePack 2 running IIS 6.0. When I published the primary site and the 2 webservices on the staging server called MOJITO I created the physical directories for each on the D drive. Then using INETMGR, I configured the following virtual directories: zVersion2 zVersion2wsSQL zVersion2wsEmergency All of the above are configured to use a new application pool I setup and named zVersion2aspNet20. The default web site for this machine MOJITO is configured to use ASP.NET 1.1 and the IP address is set to (All Unassigned). The production versions of the latter 2 webservices run on the MOJITO machine (named ZipeeeService and EmergencyService respectively). Can my staging versions of the above webservices (named zVersion2wsSQL and zVersion2wsEmergency respectively) co-exist on the same web server with the same IP address? Please note that when I test the zVersion2wsSQL webservice independently (from INETMGR right-mouse and click Browse) it works as expected (i.e. presenting all the methods of the webservice) like this snippet: GetMessageByType MessageName="Get_x0020_Message_x0020_By_x0020_Type" I can test this webmethod by clicking on it and it presents the Test dialog (because it takes a simple datatype and I am invoking it on localhost (i.e. MOJITO): **Get Message By Type** **Test** To test the operation using the HTTP POST protocol, click the 'Invoke' button. Parameter Value iMsgType: _______ [INVOKE button] SOAP 1.1 ....etc. I fear I may have rambled with too much information so I will stop but I hope someone can help me as I cannot understand why this request results in a "not found". Thanks.

• overloaded stream insertion operator with a vector

  - by Julz

  hi, i'm trying to write an overloaded stream insertion operator for a class who's only member is a vector. i dont really know what i'm doing. (lets make that clear) it's a vector of "Points" which is a struct containing two doubles. i figure what i want is to insert user input (a bunch of doubles) into a stream that i then send to a modifier method? i keep working off other stream insertion examples such as... std::ostream& operator<< (std::ostream& o, Fred const& fred) { return o << fred.i_; } but when i try a similar..... istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr.vertices; return inStream; } i get an error "no match for operator etc etc. if i leave off the .vertices it compiles but i figure it's not right? (vertices is the name of my vector ) and even if it is right, i dont actually know what syntax to use in my driver to use it? also not %100 on what my modifier method needs to look like. here's my Polygon class //header #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); public: //Constructor Polygon(const Point &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return (int) vertices.capacity();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; #endif //Body using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const Point &theVerts) { vertices.push_back (theVerts); } //Copy Constructor Polygon::Polygon(const Polygon &polyCopy) { vertices = polyCopy.vertices; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } any help greatly appreciated, sorry to be so vague, a lecturer has just kind of given us a brief example of stream insertion then left us on our own thanks. oh i realise there are probably many other problems that need fixing

(lets make that clear) it's a vector of "Points" which is a struct containing two doubles. i figure what i want is to insert user input (a bunch of doubles) into a stream that i then send to a modifier method? i keep working off other stream insertion examples such as... std::ostream& operator<< (std::ostream& o, Fred const& fred) { return o << fred.i_; } but when i try a similar..... istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr.vertices; return inStream; } i get an error "no match for operator etc etc. if i leave off the .vertices it compiles but i figure it's not right? (vertices is the name of my vector ) and even if it is right, i dont actually know what syntax to use in my driver to use it? also not %100 on what my modifier method needs to look like. here's my Polygon class //header #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); public: //Constructor Polygon(const Point &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return (int) vertices.capacity();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; #endif //Body using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const Point &theVerts) { vertices.push_back (theVerts); } //Copy Constructor Polygon::Polygon(const Polygon &polyCopy) { vertices = polyCopy.vertices; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } any help greatly appreciated, sorry to be so vague, a lecturer has just kind of given us a brief example of stream insertion then left us on our own thanks. oh i realise there are probably many other problems that need fixing

• Problem with bluetooth on android 2.1 (samsung spica i5700) where pairing works but connection does

  - by user319634

  I have a Samsung Spica i5700 which I already have updated to Android 2.1. I am using the phone with an application called Run.GPS (http://www.rungps.net). This application logs data such as GPS position, route, speed, bearing etc. It can also log heartrate provided the user has a Zephyr HxM bluetooth heart rate monitor ("HxM"), which I do have. I can pair the HxM to the phone through the standard bluetooth utility. I'm prompted for the PIN, which I enter and the device is shown as 'Paired but not connected'. In the Run.GPS application itself, I click on 'Connect Heartrate Monitor'. This times out after about 30 seconds and the error message is 'Could not connect to heartrate monitor. Please try other settings'. I used a friend's HTC Windows Mobile as a control device to see if the HxM works there. It does. The Run.GPS application automatically sets the baud rate (initially to 9600 IIRC, though the connection also worked with higher baud rates) and it is possible to choose between various COM ports as well as a .Net COM port. I did some testing on my Spica Android, to try to find out why the bluetooth connection doesn't work. Below are some log files that I connected over adb when I clicked on 'Connect to Heartrate Monitor' in the Run.GPS application. I would be interested in any tips (including if I'm posting to the wrong forum here ;-)) - whether or not it's possible to experiment with the baud rate in Android etc. I still don't know if the problem is with the Run.GPS application (I've posted already on the development forum there) or with Android 2.1. I checked out another application - Endomondo - which is also a sport tracking application which supports heartrate monitor only with the HxM. There, what looked like exactly the same error occurred - I clicked on 'Connect Zephyr HxM'. For a few seconds I was shown the 'Connecting...' status, but then it timed out into 'Not Connected'. I'm thus tending towards looking at Android for the problem. Here's the output of adb logcat while trying to connect ./adb logcat | grep Run.GPS D/WYNEX> (11551): Excute :: Run.GPS Trainer UV, (null) E/Run.GPS (11997): Cannot connect to BT device E/Run.GPS (11997): java.io.IOException: Service discovery failed E/Run.GPS (11997): at android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:374) E/Run.GPS (11997): at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:184) E/Run.GPS (11997): at ju.a(Unknown Source) E/Run.GPS (11997): at qk.j(Unknown Source) E/Run.GPS (11997): at fs.c(Unknown Source) E/Run.GPS (11997): at le.a(Unknown Source) E/Run.GPS (11997): at s.b(Unknown Source) E/Run.GPS (11997): at pb.a(Unknown Source) E/Run.GPS (11997): at as.a(Unknown Source) E/Run.GPS (11997): at am.b(Unknown Source) E/Run.GPS (11997): at gf.onTouchEvent(Unknown Source) E/Run.GPS (11997): at android.view.View.dispatchTouchEvent(View.java:3709) E/Run.GPS (11997): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) E/Run.GPS (11997): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow$DecorView.superDispatchTouchEvent(PhoneWindow.java:1665) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow.superDispatchTouchEvent(PhoneWindow.java:1107) E/Run.GPS (11997): at android.app.Activity.dispatchTouchEvent(Activity.java:2061) E/Run.GPS (11997): at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1649) E/Run.GPS (11997): at android.view.ViewRoot.handleMessage(ViewRoot.java:1694) E/Run.GPS (11997): at android.os.Handler.dispatchMessage(Handler.java:99) E/Run.GPS (11997): at android.os.Looper.loop(Looper.java:123) E/Run.GPS (11997): at android.app.ActivityThread.main(ActivityThread.java:4363) E/Run.GPS (11997): at java.lang.reflect.Method.invokeNative(Native Method) E/Run.GPS (11997): at java.lang.reflect.Method.invoke(Method.java:521) E/Run.GPS (11997): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) E/Run.GPS (11997): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) E/Run.GPS (11997): at dalvik.system.NativeStart.main(Native Method) E/Run.GPS (11997): Cannot connect to BT device E/Run.GPS (11997): java.io.IOException: Service discovery failed Here's the output of dmesg while trying to connect the heartrate monitor <4>[74726.239833] select 11691 (.serviceModeApp), adj 15, size 3205, to kill <4>[74726.240741] select 11739 (com.wssnps), adj 15, size 3207, to kill <4>[74726.246870] select 11750 (id.partnersetup), adj 15, size 3219, to kill <4>[74726.253390] select 11857 (p.bluetoothicon), adj 15, size 3299, to kill <4>[74726.259879] select 13131 (ndroid.settings), adj 15, size 4586, to kill <4>[74726.266372] send sigkill to 13131 (ndroid.settings), adj 15, size 4586 <7>[74733.945097] [BT] GPIO_BT_WAKE = 1 <7>[74733.945121] [BT] wake_lock(bt_wake_lock) <7>[74733.951799] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74733.951822] [BT] wake_lock timeout = 5 sec <7>[74735.890196] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74736.150987] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74736.151009] [BT] wake_lock timeout = 5 sec <7>[74737.490185] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74740.073913] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74740.073948] [BT] wake_lock timeout = 5 sec <7>[74741.315336] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74743.249747] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74743.249768] [BT] wake_lock timeout = 5 sec <7>[74744.865099] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74745.154487] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74745.154509] [BT] wake_lock timeout = 5 sec <7>[74748.852534] [BT] GPIO_BT_HOST_WAKE = 0 <7>[74749.156256] [BT] GPIO_BT_HOST_WAKE = 1 <7>[74749.156278] [BT] wake_lock timeout = 5 sec <7>[74750.490018] [BT] GPIO_BT_HOST_WAKE = 0 <4>[74754.230424] select 11691 (.serviceModeApp), adj 15, size 3191, to kill <4>[74754.231326] select 11739 (com.wssnps), adj 15, size 3193, to kill <4>[74754.237473] select 11750 (id.partnersetup), adj 15, size 3205, to kill <4>[74754.243950] select 11857 (p.bluetoothicon), adj 15, size 3283, to kill <4>[74754.250452] select 13140 (com.svox.pico), adj 15, size 3465, to kill <4>[74754.256787] send sigkill to 13140 (com.svox.pico), adj 15, size 3465

• Question about API and Web application code sharing

  - by opendd

  This is a design question. I have a multi part application with several user types. There is a user client for the patient that interacts with a web service. There is an API evolving behind the web service that will be exposed to institutional "users" and an interface for clinicians, researchers and admin types. The patient UI is Flex. The clinician/admin portion of the application is RoR. The API is RoR/rack based. The web service component is Java WS. All components access the same data source. These components are deployed as separate components to their own subdomains. This decision was made to allow for scaling the components individually as needed. Initially, the decision was made to split the code for the RoR Web application from the RoR API. This decision was made in the interests of security and keeping the components focused on specific tasks. Over the course of time, there is necessarily going to be overlap and I am second guessing my decision to keep the code totally separate. I am noticing code being lifted from the admin side being lifted, modified and used in the API. This being the case, I have been considering merging the Ruby based repositories. I am interested in ideas and insight on this situation along with the reasoning behind your thoughts. Thanks.

• Service-Oriented Architecture and Web Services

  Service oriented architecture is an architectural model for developing distributed systems across a network or the Internet. The main goal of this model is to create a collection of sub-systems to function as one unified system. This approach allows applications to work within the context of a client server relationship much like a web browser would interact with a web server. In this relationship a client application can request an action to be performed on a server application and are returned to the requesting client. It is important to note that primary implementation of service oriented architecture is through the use of web services. Web services are exposed components of a remote application over a network. Typically web services communicate over the HTTP and HTTPS protocols which are also the standard protocol for accessing web pages on the Internet.  These exposed components are self-contained and are self-describing.  Due to web services independence, they can be called by any application as long as it can be accessed via the network.  Web services allow for a lot of flexibility when connecting two distinct systems because the service works independently from the client. In this case a web services built with Java in a UNIX environment not will have problems handling request from a C# application in a windows environment. This is because these systems are communicating over an open protocol allowed by both environments. Additionally web services can be found by using UDDI. References: Colan, M. (2004).

• Network Logon Issues with Group Policy and Network

  - by bobloki

  I am gravely in need of your help and assistance. We have a problem with our logon and startup to our Windows 7 Enterprise system. We have more than 3000 Windows Desktops situated in roughly 20+ buildings around campus. Almost every computer on campus has the problem that I will be describing. I have spent over one month peering over etl files from Windows Performance Analyzer (A great product) and hundreds of thousands of event logs. I come to you today humbled that I could not figure this out. The problem as simply put our logon times are extremely long. An average first time logon is roughly 2-10 minutes depending on the software installed. All computers are Windows 7, the oldest computers being 5 years old. Startup times on various computers range from good (1-2 minutes) to very bad (5-60). Our second time logons range from 30 seconds to 4 minutes. We have a gigabit connection between each computer on the network. We have 5 domain controllers which also double as our DNS servers. Initial testing led us to believe that this was a software problem. So I spent a few days testing machines only to find inconsistent results from the etl files from xperfview. Each subset of computers on campus had a different subset of software issues, none seeming to interfere with logon just startup. So I started looking at our group policy and located some very interesting event ID’s. Group Policy 1129: The processing of Group Policy failed because of lack of network connectivity to a domain controller. Group Policy 1055: The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following: a) Name Resolution failure on the current domain controller. b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller). NETLOGON 5719 : This computer was not able to set up a secure session with a domain controller in domain OURDOMAIN due to the following: There are currently no logon servers available to service the logon request. This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator. E1kexpress 27: Intel®82567LM-3 Gigabit Network Connection – Network link is disconnected. NetBT 4300 – The driver could not be created. WMI 10 - Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. More or less with timestamps it becomes apparent that the network maybe the issue. 1:25:57 - Group Policy is trying to discover the domain controller information 1:25:57 - The network link has been disconnected 1:25:58 - The processing of Group Policy failed because of lack of network connectivity to a domain controller.

• IUSR account and SCCM 2007 R3 agent

  - by steve schofield

  I recently started working with SCCM and rolling the agent out with machine having IIS 7.x installed.  I ran into issues where the SCCM agent wouldn't install.  The errors mostly were 0x80004005 and 1603, another key one I found was Return Value 3 in the SCCM setup log.  During the troubleshooting, I found a cool utility called WMI Diag  WMI diag is a VBS script that reads the local WMI store and helps diagnose issue.  Anyone working with SMS or SCCM should keep this handy tool around.  The good thing my particular case WMI was healthy.  The issue turned out I changed the Anonymous Authentication module from using the IUSR account to inherit Application Pool identity.  Once we temporarily switched back to IUSR, installed the agent, then switched the setting back to inherit application pool identity, the SCCM agent installed with no issues. I'm not sure why switching back to the IUSR account solved my issue, if I find out I'll update the post.  More information on IIS 7 builtin accounts http://learn.iis.net/page.aspx/140/understanding-built-in-user-and-group-accounts-in-iis-7 Specify an application pool identity  http://technet.microsoft.com/en-us/library/cc771170(WS.10).aspx SCCM resources (Config Mgr Setup  / Deployment forums) http://social.technet.microsoft.com/Forums/en-US/configmgrsetup/threads http://www.myitforum.com (the best independent SCCM community resource) Hope this helps.
