Windows 7 Pro Client loses connectivity to internal Win2k8 web server

1. affected workstation are Optiplex 380 running Win 7 pro sp1 with broadcom NICs.
2. Internal users use a internal webserver for customer invoicing application. Users lose connectivity to this internal web server, all other networking works, network shares, internet, etc. If I try to ping the webserver IP I get no reply. XP
machines are not affected. Not a DHCP issue as there are plenty of IPs.
3. I have tried different internal NICs (3com) but still had issue. I have upgraded BIOS, nic drivers. etc.
4. I rebuilt one of the machines using Windows XP pro sp3 and have had no issue with that workstation.
the problem started a few months or so ago. I have not been able to determine the source. I tried running wireshark but nothing stuck out. I have changed the session settings on the IIS server from 15 minutes to 6 hours but did not make a difference.
5. Today when client lost connectivity to the server I tried pinging from the server back to the client and the connection was restored. This issue really has me confused as I cannot find anything in the logs that sticks out.

Hello,
Thank you for your question.
I am trying to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.
Thank you for your understanding and support.

  • Windows 7 Pro randomly loses connection to some network drives/shares.

    This is a strange one.  I can see where others are having the same issue but I have not found an answer yet so hence this post. 
    This issue is happening on a Win 7 Pro system.  As far as I know we are not having this issue on any XP systems. 
    Problem:  I have at least one Windows 7 system that every so often will lose access to network shares on our network.  It does not lose access to all mapped drives or shares just to a couple and one server in particular
    - other shares are still working fine.
    I have logged on as another user to test the profile but it has the same issue.  It doesn't matter if I try to access the mapped drive or browse directly to the share.  It will not connect.
    Once I reboot the computer, access is restored like it should be.  It will work for a few hours and then go bonkers again.   HELP!!

    Please make the following changes
    On the Server whose map drives you don't see
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters
    Value: autodisconnect
    Data type : REG_DWORD
    Value: ffff (Hex)

  • Connecting windows xp pro clients to OS X Server 10.5

    Hello, I hope I'm posting to the right place. I'm a newbie to Apple and I have a new Xserve that I need XP pro client machines to connect to. Nothing fancy, just need to be able to store files on the Xserve and print to printer(s) from my windows xp pro clients. I'm looking for a step-by-step procedure for this. The server is simple, there is currently no raid setup - just one hard drive that I would like to store files on from the windows clients. Not looking for this to be an application server or an internet server, just a central location to store files and possibly share printers. I don't really even need the Xserve to authenticate xp client logins or users. I just want to be able to connect to it and read/write files to it.
    Thank you so much for any help you can give me!!

    I was able to follow the instructions till I got to step 3. Under the Settings tab there is no Services tab at all so I can't find the SMB checkbox.
    However, on the left list there is a Windows listing and when I look at it and look under one of the tabs (forgot which one) there is an SMB checkbox for Windows sharing and it is checked along with a few other check boxes and the Guest setting is also checked.
    Is that enough or is there something else I'm missing?
    BTW, I was wrong on the OS X Server version on the Xserve. It's version 10.4.1.1.
    Thanks a bunch

  • 15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network.

    My 15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network. I have to switch off wi-fi on my Mac then switch on again to reconnect. Any reason why this random occurrence keeps happening which never happened before? Any solutions and fixes would also be welcomed.

    In the airport utility, you can alter the radio modes... and change the channels from automatic to a manual one.
    Hold down the Option key, and  click on your wifi icon, it will tell you what channels are currently being used on your OSX.

  • Replace Quotes, Connection Pooling, and Sun Web Server with MySQL, Oracle

    This is code I use to insert data into my MySQL and Oracle databases.

    This is in one class where I have a hashtable containing the
    column name / value pairs that I want to enter into my table.
    This class simply creates the SQL string from the values in the
    hashtable. It then passes that hashtable including the database
    name to a class which executes that sql statement (second code
    portion).
    /* Insert data into sf_parts. Create the column strings from
             * the provided hash table. Be sure to parse out hash elements which
             * are used for the createTemplate process
            StringBuffer values = new StringBuffer();
            StringBuffer fields = new StringBuffer();
            Enumeration keys = fieldHash.keys();
            while(keys.hasMoreElements()){
                Object currentKey = keys.nextElement();
                    String fieldValue = (String) fieldHash.get(currentKey);
                    if(values.length() >0){
                        values.append(",");
                    values.append("'"+fieldValue.replaceAll("'","''")+"'"); // Takes care of quotes and various other special characters!
                    if(fields.length() >0){
                        fields.append(",");
                    fields.append(currentKey);
            sql = "INSERT INTO myTable (" + fields.toString() + ") VALUES (" + values.toString() + ");";
            String insertResult = caq.getInsertDelete(sql,"myDatabaseName"); // your database name is defined in web.xml and sun-web.xml when you use Sun Web Server's Connection Pooling.
            returnValue += "<br><br><b>Rows inserted into table(myTable): </b>" + insertResult + "<br>\n";
            And, like I describe above, this method executes the sql statement.
         * Takes care of insert, update and delete requests.
         * Must have set both dbName as well as the sql String.
         * Will return number of rows affected as String.
         * @return String Number of rows affected
         * @exception SQLException
         * @exception Exception
        public String getInsertDelete() {
            checkData(); // this simply checks if the variables dbName and sql are not empty ;-)
            InitialContext initContext = null;
            int rv = 0;
            try{
                // Get connection from configured pool
                initContext = new InitialContext();
                source = (DataSource) initContext.lookup("java:comp/env/jdbc/" + dbName); // I have this set up in web.xml and sun-web.xml (I use Sun Web Server 6.1SP which does connection pooling for me)
                conn = source.getConnection();

    This is not a question and I am not looking for an
    answer, but please post comments or suggestions.Using prepared statements would mean that you wouldn't have to worry about quotes.
    You should be closing the result set.
    You are handling all fields as strings. That won't work with time fields and might not work for numeric fields.
    Presumably most of your variables are member variables. They should be local variables because that is the scope of the usage.
    You must do something with the exceptions.
    Hashtables although convienent mean that problems with usage can only be resolved at run time rather than compile time.

  • Windows 7 pro client cannot access folders on server 2003 domain server

    I added a windows 7 64 bit client to a server 2003 32 bit domain 3 weeks ago and file sharing was working fine until today, 5/4/12. Now, when trying to access shared folders that reside on the server,
    I get the following "access denied" message:
    […folder…] is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
    The user name could not be found.
    Strangely enough...
    The windows 7 client
    can open shared folders that reside on the XP clients in the domain
    All the XP clients in the domain can access the server 2003 folders
    All the XP clients and the server 2003 machine can access shared folders and printers on the windows 7 client.
    The windows 7 client can ping the server 2003 machine and vice versa
    I can “see” the server in my network list, but when I click on it, I get the same “access denied” message listed above.
    So... the only problem is that the windows 7 client cannot access folders that reside on the windows server 2003 machine. There must be some sharing setting that got changed
    by a recent windows update.
    Here is what I have done/verified so far on the windows 7 client:
    In advanced sharing settings for Home/Work, Public and Domain profiles:
    network discovery is enabled
    file and print sharing is enabled
    use user accounts and passwords to connect to other computers is selected (I also tried allowing windows to manage homegroup connections instead, but the problem remained.)
    40 -56 bit encryption is enabled
    In “gpedit.msc” Local Policies/Security Settings:
    enabled the following policies:
    Network access: Allow anonymous SID/name translation
    Network access: Let Everyone permissions apply to anonymous users
    disabled the following policies:
    Network access: Restrict anonymous access to Named Pipes and Shares
    Network access: Do not allow anonymous enumeration of SAM accounts
    Network access: Do not allow anonymous enumeration of SAM accounts and shares
    What am I missing? Are there policies on the server that need to be adjusted?
    Please help! My business is crippled if I cannot access server files from this workstation. Thank you in advance.

  • Using Windows NT 4.0 client program connecting to oracle 8i linux server

    Dear sir/madam,
    Recently, I have successfully installed Oracle 8i in my red hat linux database server. I am disappointed because I can find client side Oracle Enterprise Manager in my linux server even I have installed client program in my linux database server.
    Next, I install Oracle 8i client side program (windows NT/2000 version) in my Windows NT 4.0 server. I am still disappointed because I find Oracle Enterprise Manager console cannot work.
    For Windows NT 4.0 Enterprise Manager, I have key in default administrator sysman, password oem_temp, and connect to mamagement server hangng (my linux database server). An error message display 'VTK-1000 Unable to connect to the management server hangng. Please verify that you have entered the correct host name and the status of the Oracle Management Server.'.
    What's wrong with both Oracle 8i Management Server in linux database server and windows nt 4.0 server. Is there any problem for Oracle Management server console to connect to red hat linux database server?

    I saw another thread that mentioned a patch level required for 8i to let the 10g client connect. Is there such a patch level needed for 11g clients as well?There is no such patch for 8i which allows 11g client to connect.

  • Can't connect to internal Software Update Server

    Greetings All,
    I just upgraded my XServer from Tiger to Leopard. Before the upgrade, I was using the server as a Software Update Server pushing all updates to Tiger clients. Now after upgrading to Leopard and installing the Software Update Service, it seems that my Leopard (haven't tried Tiger) clients are not able to connect to it internally - they go straight to Apple. I started the service and configured the client with:
    defaults write com.apple.SoftwareUpdate CatalogURL http://10.0.1.249:8088/
    But it seems to not work. Other question is, will Tiger clients be able to connect to the Leopard server for OS updates? Thanks in advance,
    -andy-

    I've got two 10.5.4 servers (one upgraded throughout the 10.5 life-cycle and one freshly installed at 10.5.1 and combo-updated) and I've never (!!) been able to get them to connect to my Software Update Server (SUS). 10.4 clients can connect and indicate the domain in the SoftwareUpdate title bar. I can copy and paste the same command I make 10.4 clients connect into each 10.5 box I have and none of them will resolve. They all default back to Apple's servers.
    When I run "defaults read com.apple.SoftwareUpdate" I get the proper domain listed and it looks just like 10.4 client's responses. No 10.5 clients or servers will attach to my SUS. Why do 10.4 clients and servers? I even recently upgrade the SUS from 10.4.11 to 10.5.4 and Tiger clients still work, 10.5's do not.

  • Both my iMac and macbook pro will not connect to a certain web site?

    Both my macs (21" new iMac & a 2008 macbook pro) will not connect to foxcycling.co.uk. I know the site is live as I can access on my iphone and ipad.
    From what I've read on the forums its a settings issue which probably migrated from the macbook to the iMac when I migrated the data.
    Very frustrating ....
    Any idea's and simple solutions?
    Both systems up to date etc

    OK, OS X does not include Adobe Flash. The website is probably Flash based. Chrome has Flash incorporated into it. If you want to download and install Flash visit Adobe's website and download Flash for your system.

  • Using OS X Server As Internal Testing Web Server

    Hi
    First off, I'll admit it: I'm not a server bod by any stretch of the imagination. I'm a web designer/developer and we've just got a copy of OS X Server and one of the things we'd like to move away from is the developers in our company developing sites locally (using MAMP Pro) and instead, to have them develop onto OS X Server, and then deploy from that to our live web server once the site is ready to go live.
    So, I've tried setting up a few sites, and I'll be honest, I'm 100% stumped. I'm assuming that what we want can be easily handled by OS X Server; effectively, it should serve multiple virtual hosts using domain names such as test.dev etc as well as run PHP and MySQL.
    Are there any "dummies" guides out there? I assume we'll need to get to grips with the DNS and Web aspects of the Server Admin; will we also need to set up the developer Macs to get look at OS X Server for DNS too?
    So many questions, I know!! Any help greatly appreciated.
    Ta
    Phil

    From what I can see, you got the answer. Use /etc/hosts or DNS.
    That's basically how this web stuff and virtual hosting works, after all.
    The web client acquires the IP address of the web server associated with the specified host name, and it is the IP address that is used for the IP connection to the web server, and it is the host name that's passed over the http connection (as data) that's used to select a virtual host.
    AFAIK, there's no tool for this, and given you've already Googled around for it, I won't spend any time with that.
    I haven't looked at the serveradmin command line to see if adding a virtual host is feasible there from the shell, but the /etc/hosts stuff is trivial.
    Get somebody in that knows a little bash, or [go learn it yourself|http://tldp.org/HOWTO/pdf/Bash-Prog-Intro-HOWTO.pdf]. There are [Apple-specific shell and command features|http://images.apple.com/server/macosx/docs/IntroCommand_Line_Adminv10.6.pdf] available, too. This stuff could easily be part of a deployment script or makefile script and tied to your version-control system, too.
    Or sequence and write up and document the manual steps involved.
    And I'd probably punt on the whole wide-open domain-naming stuff if you're not working with the /etc/hosts approach as (with DNS) that's more work than its worth. In either case, I'd likely just use hostnames within an existing domain. Makes mistakes easier to spot when you go into production, too, as you can search for references to your domain name(s) via grep or such, and swap those for relative paths. If you unintentionally embed the customer's domain name(s), that's typically (much) harder to search for.

  • HP LaserJet Pro 200 color MFP M276nw - No Embedded Web Server (Port 80 not even showing open)

    The embedded web server on our LaserJet Pro 200 color MFP M276nw is not responding and a port scan of the printer shows that port 80 is not open. We have power cycled the printer and that did not resolve the issue. 
    Is there a way to check the status of the embedded web  server through the control panel on the printer? 
    Are there any other steps we can take to restore the embedded web server? 
    Thanks in advance. 

    Hello csandrews68,
    I see you have an LaserJet Pro 200 color MFP M276nw that the Embedded Web Server will not load, port 80 shows as closed.
    I suggest restoring the network defaults on the printer:
    From the home screen on the printer push Setup (wrench and gear icon)
    Go to and select Network Setup
    Push Restore Defaults
    With defaults restored, connect the printer back to the network and try to load the EWS.
    Let me know if that helped.
