  • Access problems with System.Diagnostics.Process in webservice

    - by Martin
    Hello everyone. I have problems with executing a process in a webservice method on a Windows Server 2003 machine. Here is the code: Dim target As String = "C:\dnscmd.exe" Dim fileInfo As System.IO.FileInfo = New System.IO.FileInfo(target) If Not fileInfo.Exists Then Throw New System.IO.FileNotFoundException("The requested file was not found: " + fileInfo.FullName) End If Dim startinfo As New System.Diagnostics.ProcessStartInfo("C:\dnscmd.exe") startinfo.UseShellExecute = False startinfo.Arguments = "\\MYCOMPUTER /recordadd mydomain.no " & dnsname & " CNAME myhost.mydomain.no" startinfo.UserName = "user1" Dim password As New SecureString() For Each c As Char In "secretpassword".ToCharArray() password.AppendChar(c) Next startinfo.Password = password Process.Start(startinfo) I know the process is being executed because i use processmonitor.exe on the server and it tells me that c:\dnscmd.exe is called with the right parameters Full command line value from procmon is: "C:\dnscmd.exe" \MYCOMPUTER /recordadd mydomain.no mysubdomain CNAME myhost.mydomain.no The user of the created process on the server is NT AUTHORITY\SYSTEM. BUT, the dns entry will not be added! Here is the weird thing: I KNOW the user (user1) I authenticate with has administrative rights (it's the same user I use to log on the machine with), but the user of the process in procmon says NT AUTHORITY\SYSTEM (which is not the user i use to authenticate). Weirdest: If i log on to the server, copy the command line value read from the procmon logging, and paste it in a command line window, it works! Reading procmon after this shows that user1 owns the dnscmd process. Why doesn't user1 become owner of the process started with system.diagnostics.process? Is the reason why the command doesn't work?

  • Find permission problem on Windows 2003

    - by Tomas
    Hello, I am trying to run process(console executable) on remote PC from asp.net application using WMI and get "Access is denied" problem. I have checked all event viewer logs on remote PC, no information related this. Where do I start searching for problem? Does Windows has some kind of permission monitor tool? Also I have tried to use Procmon.exe but hard to understand what to search, my process even do not listed in Procmon. Regards, Tomas

  • Connection Pooling is Busted

    - by MightyZot
    A few weeks ago we started getting complaints about performance in an application that has performed very well for many years.  The application is a n-tier application that uses ADODB with the SQLOLEDB provider to talk to a SQL Server database.  Our object model is written in such a way that each public method validates security before performing requested actions, so there is a significant number of queries executed to get information about file cabinets, retrieve images, create workflows, etc.  (PaperWise is a document management and workflow system.)  A common factor for these customers is that they have remote offices connected via MPLS networks. Naturally, the first thing we looked at was the query performance in SQL Profiler.  All of the queries were executing within expected timeframes, most of them were so fast that the duration in SQL Profiler was zero.  After getting nowhere with SQL Profiler, the situation was escalated to me.  I decided to take a peek with Process Monitor.  Procmon revealed some “gaps” in the TCP/IP traffic.  There were notable delays between send and receive pairs.  The send and receive pairs themselves were quite snappy, but quite often there was a notable delay between a receive and the next send.  You might expect some delay because, presumably, the application is doing some thinking in-between the pairs.  But, comparing the procmon data at the remote locations with the procmon data for workstations on the local network showed that the remote workstations were significantly delayed.  Procmon also showed a high number of disconnects. Wireshark traces showed that connections to the database were taking between 75ms and 150ms.  Not only that, but connections to a file share containing images were taking 2 seconds!  So, I asked about a trust.  Sure enough there was a trust between two domains and the file share was on the second domain.  Joining a remote workstation to the domain hosting the share containing images alleviated the time delay in accessing the file share.  Removing the trust had no affect on the connections to the database. Microsoft Network Monitor includes filters that parse TDS packets.  TDS is the protocol that SQL Server uses to communicate.  There is a certificate exchange and some SSL that occurs during authentication.  All of this was evident in the network traffic.  After staring at the network traffic for a while, and examining packets, I decided to call it a night.  On the way home that night, something about the traffic kept nagging at me.  Then it dawned on me…at the beginning of the dance of packets between the client and the server all was well.  Connection pooling was working and I could see multiple queries getting executed on the same connection and ethereal port.  After a particular query, connecting to two different servers, I noticed that ADODB and SQLOLEDB started making repeated connections to the database on different ethereal ports.  SQL Server would execute a single query and respond on a port, then open a new port and execute the next query.  Connection pooling appeared to be broken. The next morning I wrote a test to confirm my hypothesis.  Turns out that the sequence causing the connection nastiness goes something like this: Make a connection to the database. Open a result set that returns enough records to require multiple roundtrips to the server. For each result, query for some other data in the database (this will open a new implicit connection.) Close the inner result set and repeat for every item in the original result set. Close the original connection. Provided that the first result set returns enough data to require multiple roundtrips to the server, ADODB and SQLOLEDB will start making new connections to the database for each query executed in the loop.  Originally, I thought this might be due to Microsoft’s denial of service (ddos) attack protection.  After turning those features off to no avail, I eventually thought to switch my queries to client-side cursors instead of server-side cursors.  Server-side cursors are the default, by the way.  Voila!  After switching to client-side cursors, the disconnects were gone and the above sequence yielded two connections as expected. While the real problem is the amount of time it takes to make connections over these MPLS networks (100ms on average), switching to client-side cursors made the problem go away.  Believe it or not, this is actually documented by Microsoft, and rather difficult to find.  (At least it was while we were trying to troubleshoot the problem!)  So, if you’re noticing performance issues on slower networks, or networks with slower switching, take a look at the traffic in a tool like Microsoft Network Monitor.  If you notice a high number of disconnects, and you’re using fire-hose or server-side cursors, then try switching to client-side cursors and you may see the problem go away. Most likely, Microsoft believes this to be appropriate behavior, because ADODB can’t guarantee that all of the data has been retrieved when you execute the inner queries.  I’m not convinced, though, because the problem remains even after replacing all of the implicit connections with explicit connections and closing those connections in-between each of the inner queries.  In that case, there doesn’t seem to be a reason why ADODB can’t use a single connection from the connection pool to make the additional queries, bringing the total number of connections to two.  Instead ADO appears to make an assumption about the state of the connection. I’ve reported the behavior to Microsoft and am awaiting to hear from the appropriate team, so that I can demonstrate the problem.  Maybe they can explain to us why this is appropriate behavior.  :)

  • IIS6: How to troubleshoot a 404 error in an ASP.NET application?

    - by Tomalak
    I have an ASP.NET application on a Windows Server 2003/IIS6 that refuses to run for some reason (it's the Xerox Centre, if that info helps). It has been working flawlessly before though on this server. Now, all I get if I try to open the app homepage (http://some.intranet.server/XeroxCentreWareWeb/) is a "404 - File or directory not found" error. The app is configured to run in it's own app pool, which runs as Network Service. The Network Service account has read access to the configured directory. If I stop the app pool, I get the expected "Service Unavailable" message, meaning the app and its pool are wired correctly I tried to track down any file permission issues with procmon - nothing to be seen. There isn't even an access to the web app directory happening when the page loads. Interestingly, according to procmon, the web server accesses the 401-2 custom error file (Logon failed due to server configuration) first, but then decides to send the 404 down to the client. EDIT: The app runs with Windows-integrated authentication. Regular users have access to the app directory as well (I would have noticed file system "ACCESS DENIED" messages in procmon, if there had been any.) This makes me think that there is some kind of weird permission problem that occurs even before the application files are being accessed. I just have no idea where to look. I've tried to run the app pool as Local System for a test, but to no avail. What else could I check in this case?

  • SQL SERVER – Another lesser known feature of SQL Server Management Studio 2012 – Guest Post by Balmukund Lakhani

    - by Pinal Dave
    This is a fantastic blog post from my dear friend Balmukund ( blog | twitter | facebook ). He had presented a fantastic session in our last UG and there were lots of requests from attendees that he blogs about it. Well, here is the blog post about the same very popular UG session. Let us read the entire blog post in the voice of the Balmukund himself. In one of my previous guest blog on SQL Authority, I wrote about “Additional Connection Parameter” tab of login screen in SQL Server Management Studio (a.k.a. SSMS). On the similar lines, this blog is going to show little less known new feature of login main screen (“Connect to Server”) of SSMS 2012. You might have seen below screen countless times and you might wonder what is there is blog about in this simple screen. Well, continue reading and you would get the answer. Many times, DBA have to login to production server from non-regular machine, may be a developer’s workstation. Once you login to SQL, do your work and close the management studio. Do you know that your server name is saved in management studio? Of course, very useful feature because you may not like to type server name/IP address every time. Whatever servers you have connected, it would be stored by management studio. But sometime, it’s annoying! What you would do if you want SQL Server Management Studio to forget “all” the servers listed in drop down of Server name? To do that, you need to know how and where it’s stored. You can use one of my favorite tool from sysinternals called Process Monitor (also known as ProcMon) and easily figure out that this is stored in a file under your windows user profile. Below is the file in SQL 2008 R2 Management Studio. %appdata%\Microsoft\Microsoft SQL Server\100\Tools\Shell\SqlStudio.bin For SQL Server 2012, here is what we can see in ProcMon So, the path is %appdata%\Microsoft\Microsoft SQL Server\110\Tools\Shell\SqlStudio.bin So far, you might wonder, where is the new feature? I have been asked by many users to delete entries from SSMS “Connect to Server” server name list. Well, unofficially, you can delete the file directly which we found via ProcMon. Note that delete file to get rid of server list is not officially supported by Microsoft. Better way to achieve this is provided in SSMS 2012. To delete the servers from the list, highlight the name we want to delete (via keyboard or mouse) and then press delete key via keyboard. We can’t be multi-select and has to be done one by one. We can delete as many entries we want. I have delete few from first screenshot taken and here is the modified version. This is not available in SQL 2008 R2 and its previous version. This came from feedback given to SQL Server Product group. Hope you have learned something new today!

  • Is it normal for Java /Tomcat to keep checking for java_pid<nnnn>.hprof?

    - by Chris
    I was monitoring my JVM running Apache Tomcat 6, running on Windows, and I noticed that every 3 seconds or so the JVM process (C:\Tomcat\bin\tomcat6.exe) is polling to see whether or not C:\Tomcatcat\java_pid3748.hprof exists, where 3748 is the Windows process ID. I haven't seen write to the hprof file, just test for existence. (I'm using Sysinternals Process Monitor (procmon.exe) for this monitoring. In procmon the polling shows up as a QueryDirectory operation, which always returns Result "NO SUCH FILE".) Is this normal, or is this a potential red flag? I gather that these hprof files are generated, perhaps among other times, when you enable the -XX:+HeapDumpOnOutOfMemoryError Java flag. I haven't enabled it myself, though I guess it could be enabled somehow in the Tomcat startup scripts.

  • How to allow program updates without prompting UAC?

    - by Ryan Mortier
    We have about 15-20 users who have this software installed. We have UAC enabled through GPO as you should, which means the software prompts for admin approval if a standard user trys to install it. Thats fine, they can call the help desk to have the software installed. My problem is, our help desk is being bombarded every day because users can't update the software and there are updates almost every day which is prompting UAC. Using procmon.exe to find out where it was trying to write to, I then created a GPO to allow file permission access to the program files folder for this particular software, including the program data folder, but it still prompts for admin approval. It seems as though that the software is using msiexec.exe to run a .msp patch file. The only "ACCESS DENIED"s I can still see in procmon is things like this: What can I possibly do to stop this software from prompting UAC with admin password credentials aside from disabling UAC?

  • Authenticated User Impersonation in Classic ASP under IIS7

    - by user52663
    I've recently moved one of our servers from Server 2003 and IIS6 to Server 2008 R2 and IIS7 (technically IIS7.5 I suppose). In doing so I am transitioning a small account management tool written in classic ASP and have run into a problem with user impersonation. Extensive searching hasn't been much help so far. Under IIS6, the site was configured to impersonate the logged-in user. Thus, if a domain admin logged in, he was able to run commands to create user directories, adjust permissions, etc. Using Procmon you can see the processes executing as that user. This worked fine. However, with the same code under IIS7, I am unable to get this behavior. I have enabled Basic Authentication, disabled Anonymous Auth, enabled impersonation and have changed the app pool to classic instead of integrated pipelining. Everything seems to be configured correctly, however, all the processes launched by the classic ASP site continue to run as the default AppPool identity and not the logged-in user. If it matters, programs are being launched with code such as: set Wsh = Server.CreateObject("WScript.Shell") Wsh.Run("cmd.exe /C mkdir D:\users\foo") Monitoring via Procmon shows cmd.exe being run as either "Classic .NET AppPool" or "DefaultAppPool" depending on the pipeline mode. Any suggestions on how to get the classic ASP site to impersonate and execute as the authenticated user would be great. Thanks!

  • IIS 7.5, ASP.NET, impersonation, and access to C:\Windows\Temp

    - by Heinzi
    Summary: One of our web applications requires write access to C:\Windows\Temp. However, no matter how much I weaken the NTFS permission, procmon shows ACCESS DENIED. Background (which might or might not be relevant for the problem): We are using OLEDB to access an MS Access database (which is located outside of C:\Windows\Temp). Unfortunately, this OLEDB driver requires write access to the user profile's TEMP directory (which happens to be C:\Windows\Temp when running under IIS 7.5), otherwise the dreaded "Unspecified Error" OleDbException is thrown. See KB 926939 for details. I followed the steps in the KB article, but it doesn't help. Details: This is the output of icacls C:\Windows\Temp. For debugging purposes I gave full permissions to Everyone. C:\Windows\Temp NT AUTHORITY\SYSTEM:(OI)(CI)(F) CREATOR OWNER:(OI)(CI)(IO)(F) BUILTIN\IIS_IUSRS:(OI)(CI)(S,RD) BUILTIN\Users:(CI)(S,WD,AD,X) BUILTIN\Administrators:(OI)(CI)(F) Everyone:(OI)(CI)(F) However, this is the screenshot of procmon: Desired Access: Generic Read/Write, Delete Disposition: Create Options: Synchronous IO Non-Alert, Non-Directory File, Random Access, Delete On Close, Open No Recall Attributes: NT ShareMode: None AllocationSize: 0 Impersonating: MYDOMAIN\myuser

  • HtmlAgilityPack - Vs 2010 - c# ASP - File Not found

    - by Janosch Geigowskoskilu
    First, I've already searched the web & StackOverflow for hours, and i did find a lot about troubleshooting HtmlAgilityPack and tried most of these but nothing worked. The Situation: I'm developing a C# ASP .NET WebPart in SharePoint Foundation. Everything works fine, now I want to Parse a HTML Page to get all ImagePaths and save the Images on HD/Temp. To do that I was downloading HtmlAgilityPack, current version, add reference to Project, everything looks OK, IntelliSense works fine. The Exception: But when I want to run the section where HtmlAgilityPack should be used my Browser shows me a FileNotFoundException - The File or Assembly could not be found. What I tried: After first searches i tried to include v1.4.0 of HtmlAgilityPack cause I read that the current version in some case is not really stable. This works fine to until the point I want to use HtmlAgilityPack, the same Exception. I also tried moving the HtmlAgilityPack direct to the Solution directory, nothing changed. I tried to insert HtmlAgilityPack via using and I tried direct call e.g. HtmlAgilityPack.HtmlDocument. Conclusion : When I compile no error occurs, the reference is set correct. When I trace the HtmlAgilityPack.dll with ProcMon the Path is shown correct, but sometimes the Result is 'File Locked with only Readers' but I don't know enough about ProcMon to Know what this means or if this is critical. It couldn't have something to do with File Permissions because if I check the DLL the permissions are all given.

  • Cannot Send Item error in Outlook - permissions to registry?

    - by Tim Alexander
    The issue I am trying to solve is to do with users getting a Cannot Send Item error in Outlook 2007 connecting to Exchange 2007. Basically if there is an image in the email (either one they have pasted in or one from another email in the chain) they get a "Cannot Send Item" error. Initially thought it was a citrix issue but users get it when they RDP to a server as well. Changing the message to Rich Text works 80% of the time but I do not think this is a solution but more of a temporary workaround. After some troubleshooting we found that the error can be fixed by adding the user as a member of the local power users group. of course this is not really a fix. My thoughts were that the ability of a power user to add/remove software may give them more access to the registry which might allow them to get round a restriction that is in place for a normal user. I have tried going through a procmon but the wealth of information is confusing. It initially looked like it may be an Outlook 2007 email security setting but this does not change between power user and normal user (set to 1 in the registry, "Use the security setting from Outlook Security Settings Public Folders"). I am struggling to fine tune my troubleshooting to work out exactly what is blocking it. Has anyone had an experience with an error similar to this? Or are there any tips for trying to track down issues via procmon as I must admit my approach seems somewhat lacking :) EDIT: So I have trawled through the two logs we have from process monitor (one as a power user and one a normal user). annoyingly I can find no obvious difference where something is denied access. There are more access denied events in the normal user log but these are quickly followed by sucessful entries to the same path fractions of a second later. The only thing that does stand out is an access denied to HKCR.html. This does not even appear in the power user version of the log. From what I understand this helps determine the default browser which ties in nicely with the fact that 9 out of 10 times you can send the message as Rich Text. EDIT: Looks like KB2509470 was causing the issue. Not really sure why but when I can work out what it does and why it causes the problem will post here unless anyone beats me to it!

  • Asynchronous File I/O in .NET

    - by uno
    I followed the example at this link, Async I/O). The example works on my local machine. However when I deploy to my test machine - Windows Server 2003, It seems to work on 24 files and then the application stops. Procmon shows that its working on 24 files and then there is no data. My local machine is Windows XP. The question is why would this behave this drastically between XP and Windows 2003

  • 401 - Unauthorized On Server 2008 R2 IIS 7.5

    - by mxmissile
    I have a web application deployed to Server 2008 IIS 7.5 box. From remote it gives this error: 401 - Unauthorized: Access is denied due to invalid credentials. (remote = desktops on the same LAN) Have tried several remote clients using different browsers, all the same result. (IE, FF, and Chrome) Hitting the application from the desktop of the server itself works flawlessly. The application is using Anonymous Authentication. The application is written in .NET 4.0 Asp.Net using the MVC framework. Sysinternals procmon returns these 2 results for each request: FAST IO DISALLOWED and PATH NOT FOUND. I have 2 other MVC apps running fine on the same server. I have checked the security on the folders and they all match. App runs fine on a Server 2008 IIS 7.0 box. Nothing shows up in the Event log on the server related to this. Pulling my hair out here, any troubleshooting tips?

  • Unexpected Access Denied error while accessing EFS encrypted file

    - by pozi
    I am getting Access Denied error when I try to access some files. ACL is OK, all ACE's all intherited, I have full access to these files and I am the owner of these files. ACE's are exactly same as other files in the same directory which are accessible without problems (doublechecked through Security Tab on file properties and cacls command). Files are EFS encrypted, however I should have access to these files, because they were encrypted by the same user account I am trying to access (decrypt) them. EFS settings are exactly same as other files in the same directory which are also encrypted and accessible without problems (doublechecked through cipher command and efsdump command (SysInternals)). In ProcMon utility (SysInternals) I am getting Access Denied entry while accessing these files. Files are not used (locked), checked by Unlocker utility. Up to now, I tought I understand NTFS ACL's and EFS mechanisms fairly well, but now I am completely stuck and I do not know how to access these files. Any thoughts?

  • Java application crashes my computer. How do I troubleshoot?

    - by Oded
    I am using NetBeans 4.1 for my university course (this is an older version, but is the required version for the course - I can't use a newer version). Whenever I use it for longer than several minutes, my computer crashes - it either reboots or I need to reset it. I have tried running with all startup items disabled (to rule out other applications interfering with the app), but it did no good. I have used Sysinternals procmon logging and the logs are corrupt - the only way I was able to get a good log was by enabling boot logging. However these are huge and I don't know what to look for. I am using Windows XP SP3, fully patched up and this is the only application that I have any kind of problem with. Can anyone suggest troubleshooting steps that will help me pinpoint the cause of these crashes and fix them?

  • Intuitive view of what's using the hard drive so much on Windows 7?

    - by Aren Cambre
    Sometimes my hard drive usage is near 100%, and I have no idea what is causing it. Are there any utilities that can help diagnose excessive hard drive usage and have as intuitive of an interface as Task Manager's Processes tab, which I can sort by CPU usage? I am aware of using procmon, of adding columns to Task Manager's Processes tab like I/O Read Bytes and I/O Write Bytes, and using Resource Monitor's Disk tab. Too often, these don't give me useful information or clearly identify a single process that is hogging the disk.

  • Overrideen ASPNet.config does not apply for legacyImpersonationPolicy

    - by Grumbler85
    I tried to override the <legacyImpersonationPolicy> Element, so a single application, will enable this policy (which is necessary, since this application breaks if disabled). So my Framework64/aspnet.config states: <configuration> <runtime> <legacyUnhandledExceptionPolicy enabled="false" /> <legacyImpersonationPolicy enabled="false" /> <alwaysFlowImpersonationPolicy enabled="false" /> <SymbolReadingPolicy enabled="1" /> <shadowCopyVerifyByTimestamp enabled="true"/> </runtime> <startup useLegacyV2RuntimeActivationPolicy="true" /> </configuration> And a local aspnet.config file has this change: <legacyImpersonationPolicy enabled="false" /> Procmon tells me the file is read by the w3wp.exe, but the settings will not apply. Can anyone point out a way how to correctly override the setting? *The Server has been restarted meanwhile, but still no changes.

  • Trying to right click on code in VS2008 causes lockup.

    - by Adam Haile
    Working on a Win32 DLL using Visual Studio 2008 SP1 and, since yesterday, whenever I try to right click on code, to go to a variable definition for example, VS completely locks up and I have to manually kill the process. To make it even weirder, whenever this happens the devenv.exe process uses exactly 25% of the CPU. And I mean exactly, never 24%, never 26%, always 25% Also, I've run ProcMon to see if devenv is actually doing something, but it's doing absolutely nothing external of the process. No disk, network, registry access. Nothing. This is getting really aggravating because I have a large code base to deal with and the only other way of jumping to the definition is to first search for it. Has anyone run into a similar issue? And, better yet, know a fix?

  • Certificate Revocation checking affecting system performance [migrated]

    I have a .NET 3.5 desktop application that had been showing periodic slow downs in functionality whenever the test machine it was on was out of the office. I managed to replicate the error on a machine in the office without an internet connection, but it was only when i used ANTS performance profiler that i got a clearer picture of what was going on. In ANTS I saw a "Waiting for synchronization" taking up to 16 seconds that corresponded to the delay I could see in the application when NHibernate tried to load the System.Data.SqlServerCE.dll assembly. If I tried the action again immediately it would work with no delay but if I left it for 5 minutes then it would be slow to load again the next time I tried it. From my research so far it appears to be because the SqlServerCE dll is signed and so the system is trying to connect to get the certificate revocation lists and timing out. Disabling the "Automatically detect settings" setting in the Internet Options LAN settings makes the problem go away, as does disabling the "Check for publishers certificate revocation". But the admins where this application will be deployed are not going to be happy with the idea of disabling certificate checking on a per machine or per user basis so I really need to get the application level disabling of the CRL check working. There is the well documented bug in .net 2.0 which describes this behaviour, and offers a possible fix with a config file element. <?xml version="1.0" encoding="utf-8"?> <configuration> <runtime> <generatePublisherEvidence enabled="false"/> </runtime> </configuration> This is NOT working for me however even though I am using .net 3.5. The SQLServerCE dll is being loaded dynamically by NHibernate and I wonder if the fact that it's dynamic could somehow be why the setting isn't working, but I don't know how I could check that. Can anyone offer suggestions as to why the config setting might not work? Or is there another way I could disable the check at the application level, perhaps a CAS policy setting that I can use to set an exception for the application when it's installed? Or is there something I can change in the application to up the trust level or something like that? I have also tried using to no advantage ServicePointManager.CheckCertificateRevocationList = false; http://rusanu.com/2009/07/24/fix-slow-application-startup-due-to-code-sign-validation/ I have also tried those registry settings out and unfortunately they didn't help. The dlls that appear to be the cause of the hold up are native SQL Server CE dlls, and looking at the stack traces in ProcMon mscorwks.dll doesn't appear to be involved even though the checks on crypto and cert registry keys are being done under the .NET application. It's definitely still something to do with publisher certificate checking because unticking "Check for publisher revocation certificate" still works but something odd is going on.
