  • Random servers in Citrix servers suddenly bluescreens (mostly 0x0000008e and 0x0000007e)

    - by Rasmus Rask
    I'm responsible for a Citrix Presentation Server 4.5 farm. Starting Friday 30. November, my servers started to crash randomly. So far we've experienced 80 crashes, so it's obviously becoming an increasingly big problem for us. I have 12+ years experience with IT, so I know the difference between 0 and 1, but I have a hard time cracking this. We've rolled back any recent changes I can think of for different groups of servers, but all groups still seem to crash. I don't have the skills to interpret the memory dumps to find the culprit. Has anyone encountered the same or a similar problem? - might be a generic Windows issue Other than executing "analyze -v" in WinDbg, how do I work my way through the memory dumps to see what actually triggered the BSOD? Any suggested steps in getting to the bottom of this? Any help is greatly appreciated. I can also provide links to kernel memory dumps or WinDbg output if necessary. Thanks! Problem description The majority of the STOP errors we encounter are: 0x0000008e KERNEL_MODE_EXCEPTION_NOT_HANDLED (50%) 0x0000007e SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (26%) 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA (21%) We also see a few 0x0000000a IRQL_NOT_LESS_OR_EQUAL (3%). For both 0x0000008e and 0x0000007e bug checks, the exception code is 0xc0000005 (Access Violation). When opening dump files in WinDbg, most details are exactly the same, for all the 0x0000008e and 0x0000007e bug checks respectively: 0x0000008e Exception address: 0x808bc9e3 Trap frame: [varies] FAILURE_BUCKET_ID: 0x8E_nt!HvpGetCellMapped+97 Probably Caused by (IMAGE_NAME): ntkrpamp.exe 0x0000007e Exception address: 0x808369b6 Exception record address: 0xf70d3be0 Context record address: 0xf70d38dc FAILURE_BUCKET_ID: 0x7E_nt!MmPurgeSection+14 Probably Caused by: memory_corruption About 30% of the crashes happens between 17:00 and 19:00, which leads me to believe this tend to happen more often during logoffs. But then again, only ~15% occurs between 15:00 and 17:00. Summary of farm Citrix Presentation Server 4.5 R06 on Windows Server 2003 R2 SP2 All high priority patches, at least as of October installed Virtualized using VMWare ESX/vSphere 4.1 on HP Proliant BL460c G6 blade servers About 53 Presentation Servers in production, divided into three silos - only one of which, the largest, is affected 2 vCPU's (5 GHz reserved), 8 GB RAM (all reserved) for each Presentation Server Plenty of free disk space Very few printer drivers - automated deletion of non-approved drivers every night ~1.000 peak concurrent users, which is reached at around 10:30 (on weekdays) Number of sessions steadily decline between 15:00 and 19:00 to ~230

  • Uploadify Flash Uploader and Random UPLOAD_ERR_CANT_WRITE errors

    - by dcneiner
    I am using Uploadify to provide progress bar support for file uploads on a PHP app I built. It works perfectly for a few uploads,then every few uploads it fails and the data from the $_FILES array reveals an UPLOAD_ERR_CANT_WRITE error. (Error code 7). I ran Paros proxy between my browser and the server to see the difference between a passing and failing request. The only difference was the content separator for the multi-part post which changes every time. I would conclude this was fully a server error, except with a plain jane form, I cannot reproduce the error. I am not a server guy, so please let me know what information is needed to troubleshoot this and I will update the question with those details. I did place these lines in the .htaccess, but to know avail. The site is hosted on Rackspace Cloudsites so my configuration options are limited: <IfModule mod_security.c> SecFilterEngine Off SecFilterScanPOST Off </IfModule> php_value upload_max_filesize 10M php_value post_max_size 10M php_value max_execution_time 200 php_value max_input_time 200

  • SNMPD running but not listening for connections at random

    - by Lukasz
    OS: CentOS release 5.7 (Final) Net-SNMP: net-snmp-5.3.2.2-14.el5_7.1 (from RPM) Periodically my NMS notifies me that SNMP has gone down on this machine. The service is restored in between 10 to 30 minutes. My NMS also pings and check SSH and those services are not affected during the SNMP outage. SNMPD log file shows that it is working and apparently receiving packets (either from local agents from 127.0.0.1 or from my NMS at 172.16.37.37) however attempting to snmpwalk locally or from the NMS system fails with a timeout. I have 7 of these servers running mixture of CentOS 5.7 and RHEL 5.7 with this specific version of Net-SNMP installed from RPM - none of them have this issue except this one. 5 of the machines (including the NMS system and this problem server) are in the same rack connected using one switch. Restarting SNMPD does not fix the issue - it clears up by itself eventually. Any suggestions where I can begin diagnosing the issue? It's a closed subnet so IPTables is not used.

  • Dell e4300 Random Beeps

    - by Mikey.B
    I’ve noticed that my Dell e4300 Laptop will randomly beep every now and then. The symptoms are virtually identical to the issue described here: http://en.community.dell.com/support-forums/laptop/f/3518/t/19314488.aspx Any ideas why? I thought it might be related to hard drive activity so I downloaded the western digital disk utility and all tests check out fine. It’s not a big deal and it only beeps once every few days. I just want to make sure there isn’t a larger problem looming. =) -M

  • VMware Server Guest OS Random Shutdown

    - by radioactive21
    Anyone encounter a problem in which the Guest OS in VMware Server randomly shuts down? This has happened about once a month, where VMware Server just shuts down ALL guests OS. The host machine is fine, and you can log into the web management of VMware Server, it's just all guest OS get shutdown with no apparent reason. Even the logs say vmware guest os so and so was shut down, but no details why. This is not just one one machine, we have VMware server installed on three different PowerEdge servers and they all have encounter the same problem. We've tripped checked all settings and nothing is out of the ordinary.

  • Nginx + PHP-FPM = "Random" 502 Bad Gateway

    - by david
    I am running Nginx and proxying php requests via FastCGI to PHP-FPM for processing. I will randomly receive 502 Bad Gateway error pages - I can reproduce this issue by clicking around my PHP websites very rapidly/refreshing a page for a minute or two. When I get the 502 error page all I have to do is refresh the browser and the page refreshes properly. Here is my setup: nginx/0.7.64 PHP 5.3.2 (fpm-fcgi) (built: Apr 1 2010 06:42:04) Ubuntu 9.10 (Latest 2.6 Paravirt) I compiled PHP-FPM using this ./configure directive ./configure --enable-fpm --sysconfdir=/etc/php5/conf.d --with-config-file-path=/etc/php5/conf.d/php.ini --with-zlib --with-openssl --enable-zip --enable-exif --enable-ftp --enable-mbstring --enable-mbregex --enable-soap --enable-sockets --disable-cgi --with-curl --with-curlwrappers --with-gd --with-mcrypt --enable-memcache --with-mhash --with-jpeg-dir=/usr/local/lib --with-mysql=/usr/bin/mysql --with-mysqli=/usr/bin/mysql_config --enable-pdo --with-pdo-mysql=/usr/bin/mysql --with-pdo-sqlite --with-pspell --with-snmp --with-sqlite --with-tidy --with-xmlrpc --with-xsl My php-fpm.conf looks like this (the relevant parts): ... <value name="pm"> <value name="max_children">3</value> ... <value name="request_terminate_timeout">60s</value> <value name="request_slowlog_timeout">30s</value> <value name="slowlog">/var/log/php-fpm.log.slow</value> <value name="rlimit_files">1024</value> <value name="rlimit_core">0</value> <value name="chroot"></value> <value name="chdir"></value> <value name="catch_workers_output">yes</value> <value name="max_requests">500</value> ... I've tried increasing the max_children to 10 and it makes no difference. I've also tried setting it to 'dynamic' and setting max_children to 50, and start_server to '5' without any difference. I have tried using both 1 and 5 nginx worker processes. My fastcgi_params conf looks like: fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REDIRECT_STATUS 200; Nginx logs the error as: [error] 3947#0: *10530 connect() failed (111: Connection refused) while connecting to upstream, client: 68.40.xxx.xxx, server: www.domain.com, request: "GET /favicon.ico HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.domain.com" PHP-FPM logs the follow at the time of the error: [NOTICE] pid 17161, fpm_unix_init_main(), line 255: getrlimit(nofile): max:1024, cur:1024 [NOTICE] pid 17161, fpm_event_init_main(), line 93: libevent: using epoll [NOTICE] pid 17161, fpm_init(), line 50: fpm is running, pid 17161 [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17162 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17163 started [DEBUG] pid 17161, fpm_children_make(), line 403: [pool default] child 17164 started [NOTICE] pid 17161, fpm_event_loop(), line 111: ready to handle connections My CPU usage maxes out around 10-15% when I recreate the issue. My Free mem (free -m) is 130MB I had this intermittent 502 Bad Gateway issue when in was using php5-cgi to service my php requests as well. Does anyone know how to fix this?

  • Semi-random clicking sound from Macbook Pro

    - by Justin Love
    There is an occasional click sound coming from my Macbook Pro (17", 2.2 Ghz Core 2 Duo) I upgraded to Snow Leopard recently, but the computer was also in for service about week before that, so I can't be certain the OS upgrade is related. The sound has no set interval and frequency varies from rare to every few seconds. I can alleviate the sound by turning up the fan speed with smcFanControl. Turning the right fan up about half way seems to be sufficient. Unfortunately, turning up the left fan also causes the right to turn on, because the sound seems to be slightly more to the left. The cause seems to be either a fan or heat-related.

  • FTP transfer hangs for random files

    - by hoffmandirt
    I've been stuck on this FTP issue for a while now. I have IIS 7 setup with an IIS 6 FTP server running on a Windows Server 2008 box. The problem I am running into is that I can't download certain files from the FTP server, even though I uploaded those files to the FTP server. The connection times out after 120 seconds. I have used Wireshark and checked the log files. The only message I see is the timeout message. The first thing that came to my mind was permission issues, however I have probably tried every combination of permissions that I can think of, with the end goal of getting the permissions to be the same for the files that work and the files that do not work. With the list of files I have now, I can download the zip, war, and msi files, but not the txt or sql files. It almost seems like a binary thing, but I've changed my transfer mode on the FTP client and also toggled the Active/Passive options around.

  • Weird random application hang problem

    - by haridsv
    I am trying to understand an application hang problem that started up lately on my windows xp system. The system runs fine for days (sometimes) without ever shutting down or putting it to sleep, but the problem first shows up as one of the apps hanging. The application's UI stops responding or one or more background threads hang, so even though the GUI is responding, it is not doing anything (e.g., in VirtualDub's case, the UI responds fine, but the job doesn't progress and I won't even be able to abort it). The weirdness part comes from the fact that if I try to kill such an app, the program that is used to kill it goes into the same mode (i.e, that hangs instead of the original). E.g., if I use Process Explorer to kill it, the original program exits, but procexp now hangs. If I use another instance of procexp to kill the one that is hanging, this repeats, so there is always at least one program hanging in that state. This is not specific to procexp, I tried the native task manager and even the "End Process" dialog from windows explorer that shows up when you try to close a non-responsive GUI (in this case, the explorer itself hangs). The only program that didn't hang after the kill, is the command line taskkill. However, in this case, explorer hangs instead of taskkill. Also, once this problem starts manifesting, it soon ends up freezing the whole system to the extent that even a clean shutdown is not possible, so I have learned to reboot as soon as I notice this problem, however this is very inconvenient, as I often have encoding batch jobs going on which can't continue the job after the restart. The longer I leave the system running after seeing this problem, the more applications get into this state. I have tried to do a repair install but that didn't make any difference. I also uninstalled some of the newer installs, but again no difference. I tried to search online, but got inundating results for generic hang and crash related problems. Though I couldn't notice any pattern, it seems as though the problem is more frequent if I have some video encoding going on at that time. I had the system running for days when I only do browsing and internet audio/video chat before I decide to start encoding something and the problem starts to show up. I am not too sure if it is the encoding program that first hangs, though I almost always noticed that too hanging (like the VirtualDub stopping to make progress). I also had to reboot 3 times on one day when I was heavily experimenting with encoding. I would appreciate any help in narrowing down this problem and save me the trouble of reinstalling. I don't especially want to loose my gotd installs.

  • IIS 8 Random 503 service unavailable

    - by Ivo
    We migrated a busy website to Windows Server 2012 with IIS 8. The website randomly gives the error "503 service unavailable" after an user presses F5 the error is gone again. The website is build in ASP.NET MVC 3. The website runs on one application pool, with default settings There are around 500 to 900 concurrent users on the website during the day, and the error happens more often when there are more 650 users. The CPU and the memory use on the server is stable. There is nothing about the 503 errors in the application log, the IIS log and the event log. Does anyone has any clue what the problem can be or how we can trace the the problem?

  • OS X random, jumpy dragging behavior

    - by Chris
    This problem has been going on since I got 10.7, and is persisting or even getting worse since I updated to Mavricks. The best way to describe it is thru an example- Let's say I'm working in Safari. Everything is working fine. Then, I'll switch to another app by clicking on it's window, for example, I'll click on Messages to shoot back a reply. When I click back to Safari, keyboard and mouse inputs don't work! The only way I can regain control of the app (Safari) is by clicking on the apps top bar, which then causes the app to jump left or right. If I'm in Messages and I switch back to Safari by clicking said top bar, it works fine. Same with switching back and forth using command-tab. I've narrowed the problem down to this - the first app (Safari, in this example) is, for some reason, deciding that I'm in the process of dragging the window around. This could be just an oddly persistent glitch in my system, but has anyone else seen this before? Perhaps a misplaced default write... somewhere along the line? Update A PRAM reset did absolutely nothing

  • Random Slow Response

    - by ARehman
    We have an ASP.NET MVC 1.0 application running on Windows Server 2008 – Standard (32 –bit), Dual Core Xeon (3.0 GHz), 2 G.B R.A.M. Most of the times application renders response in 3-4 seconds, but sometimes users get very late response and delay is up to 40 seconds or more than a minute. It happens in following way: User browsed a page, idle for 5, 10 or 15 minutes, tried to browse same page or some other. Now, there is a chance that he will see late response whereas the app pool is still up and running. This can happen with any arbitrary page. We have tried followings/observations. Moved the application to stand alone web server App Pool idle shutdown time is 60 minutes. There are no abrupt shut downs/restarts. CPU or memory doesn’t spike. No delays in SQL queries. Modified App Pool setting to run in classic-mode. It didn’t help. Plugged-in custom module to log all those requests which took more than 5 seconds to complete. It didn’t pick any request of interest. Enabled ‘Failed Request Tracing’ to log all those requests which take 20 or more seconds to complete. It didn’t log anything. Event Viewer, HTTPER log, W3SVC logs or WAS logs don’t indicate anything. HTTPERR only has ‘_ _ Timer_ConnectionIdle _ _’ entries. There is not much traffic to server. This can happen also if only two users are active. Next we captured TCP/IP terrific on both a user and server end with Wireshark and below are details in brief of this slowness: Browser sends a request for ~/User/Home/ (GET Request) by setting up a receiving end point using port 'wlbs(port-2504)'. I'm not sure if this could be a problem in some way that browser didn't hand-shake with the server first and assumed that last connection is still open, whereas, I browsed the same page 4 minutes ago and didn't perform any activity with site after that. If I see the HTTPERR log, it indicates that it has ‘_ _ Timer_ConnectionIdle _ _ _’ entry for my last activity with server. Browser (I was using Chrome) waits for any response from the server, doesn’t find any then starts retransmitting the same request using same end point after incrementing wait intervals, e.g. after 8, 18, 29, 40, 62, and 92 seconds. All these GET requests were received by server as well. But, server didn’t send any packet to client. Browser didn't see any response on the end point it set up in point 1, it opened a new end point 'optiwave-lm (port-2524)', did a hand shake with the server and transmitted the same request again. Server received, processed it, and returned successful response. What happened to earlier 6-7 requests? Whether they were passed on to HTTP.SYS or not? Why Failed Request Tracing not logged anything, we didn't find any clue yet. Server served the same page successfully just 4 minutes ago. Looking forward for more suggestions/solutions. -- Thanks

  • How to stop a random ramp in FCGI Processes Killing the server

    - by Andy Main
    So got the below earlier to day... Around that time the logs show a ramp in processes(600) and associated memory (1.2g), cpu usage load average (80) untill the server gave out. Server had to be hard reset by host as there was no ssh or plesk panel access. Fast CGI is configured as below and is setup for one high use site. As I understand it FcgidMaxProcesses 20 should protect against what happen but has not. I've read many forums with differing answers and references to many different fcgi directives, but have found nothing conclusive. Any one got some definitive answers on how to stop this sort of server process ramping and subsequent server failure? If you need more info let me know.

  • System chooses boot drive seemingly at random

    - by Zurahn
    I have a system with two identical 1TB harddrives, where I image to a backup drive using the dd command. When I boot up, though, despite setting harddrive priority in the BIOS, the system sometimes boots the main drive, sometimes boots the backup. My system dual-boots Xubuntu and Windows XP, if that means anything to you. Any ideas?

  • Wireless disconnects at random after upgrade to Ubuntu 10.4

Even though the server drops out, everything else on the network keeps working like normal.

  • Magnetic Stripe Reader over Terminal Server has random Uppercase/Lowercase nonsense

    - by Peter Turner
    The Magnetic Stripe Reader that I'm using and testing is just supposed to be sending keystrokes. Unfortunately, it seems to randomly be sending upper case and lower case keystrokes, sometimes substituting % for 5 and ^ for 6 and vice versa. (If you've ever programmed for a magnetic strip reader, you know that's not a good thing.) Is there something in the RDP protocol that causes this? I've got kind of a convoluted system, running XP inside virtualbox on Fedora 11 RDP'ed into a win2k3 server. It works on the XP VM and it doesn't work on the RDP'ed one. What's weirder, is that I'm not even emulating the USB drivers for my Mag Card Reader. Linux is sending keystrokes straight in to windows, and MSTSC on windows XP is sending crap to the Win2k3 server. I'm 99% certain this isn't a problem with the card reader, it has nothing to do with my programming either. (I get the same junk coming into notepad that I get coming into our software [that's why I didn't ask on SO]). And, it works with rdesktop programs other than MSTSC.exe! Needless to say, I'm in need of some RDP Guruship.

  • NginX & PHP-FPM, random 502.

    - by pestaa
    2010/09/19 14:52:07 [error] 1419#0: *10220 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: [...], server: [...], request: "POST /[...] HTTP/1.1", upstream: "fastcgi://unix:/server/php-fpm.sock:", host: "[...]", referrer: "[...]" This is the error I'm receiving randomly. 95% of the time my setup works perfectly, but once in a while I'm getting 502 for 3-4 subsequent requests. I'm using Unix socket between the server and the PHP process as you can see, also have set up FastCGI params (SCRIPT_FILENAME), etc. correctly. What can I do about it to strengthen the connection between these services? Thank you very much in advance.

  • Stop the constant random reboots of my GIGABYTE GA-B75M-D3V

    - by Frederic
    I've got some issues with a new system. It's rebooting constantly. The system consists of a: brand new: Gigabyte GA-B75M-D3V with F9 BIOS (latest) Intel Core i5-3470 Ivy Bridge 2x 8GB G.SKILL Ripjaws 1600MHz memory (mem-tested x-86) coming from a stable system: Creative Soundcard X-FI Titanium Asus Radeon HD4850 OCZ Vertex 3 120G SSD Sata 3 Hard disk 1TB Sata 2 ASUS Blu-ray Drive PSU 400w Connected peripherals : Toshiba tv (displayport on dvi of MB or HD4850) Wired mouse, wireless keyboard (logitech) Bluetooth usb key Azio main problem : it's not possible to read the errors from the MB. nothing on the manual neither on internet. At the beginning, I received a MB with graphic problems and the problem of rebooting. I RMA'd it. The new one doesn't have any graphic problems. but it's still constantly rebooting. I removed everything except the HD, the sound-card, the blu-ray drive and the wireless keyboard. It's still unexpectdly rebooting. I'm running a test with just the motherboard and the HD. I will update this text after the test. I've got some questions : Somebody have an idea of a test? The PSU could cause that problem? I used it a lot of years with the stable system. Update 1: BTW, if anyone has the same problem, the manual won't say it but you'll need to reset the bios between two tests (the screwdriver on the two pins) if you suspect a problem of compatibility .

  • diagnosing random power down crashes on a hackintosh [closed]

    - by Iain
    I have a hackintosh running on a Gigabyte P55M UD2. It has run without a single issue as a hackintosh for about 9 months, and the machine is about 2.75 years old. Never had issues when it was just linux box. Power supply is 750 Watts. It recently started spontaneously rebooting, no seeming connected to any particular use case or ram/cpu load. There is no hanging or anything, just suddenly acts like the power went out. The frequency of which seems to be increasing. I've tried using just one of each of the two ram sticks, and it happens with either one in. I'm not sure what to try next, is there some way of determinging whether it's a mobo, cpu, or powersupply issue short of replacing them all? thanks! Iain

  • Seemingly random network connectivity.

    - by AngryHacker
    This has been driving me nuts for a while. When I turn on the PC (which has a wired Ethernet connection), it cannot be accessed by other computers on the network. In other words, inbound connections do not work. The firewall is disabled. The PC itself can hit up anything it wants just fine. By process of elimination, I've figured out that checking or unchecking the Eaclift driver in the properties for my network connection restored the inbound connection. I do not know what Eaclift driver is or does or how it even got on my PC (e.g. I am not allowed to uninstall it either). And it does not matter whether it's on or off - I just need to toggle it to restore connectivity. One other thing that happens when I toggle the Eaclift driver, is than an Internet Connection icon appears in the Network Connections and it was not there before. Can someone shed some light as to what is going on? How to fix it so that I don't have to deal with this insanity?

  • Random users randomly being unable to connect to my static content domain

    - by jls33fsls
    I store all of my images, js, and css files on a separate domain to try and speed up page load times (it isn't a CDN, just a separate domain on the same server). This works fine for 99% of the users, 99% of the time. However, there are users that randomly are unable to connect to the static content domain for periods of 1-5 hours. They can go to the main site, but no images will load and everything is just white because no css is being loaded. If they go to the static content domain itself, the page just idles for a while and then times out with a blank white page, no error messages. I have no idea what could be causing this, and it hasn't happened to me, any ideas? I am running Apache on CentOS 5.5.

  • Tracking down random BSOD on windows 7

    - by pehrs
    I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

  • Can we put random URL entries on DNS

    - by ring bearer
    Using microsoft DNS All/most of our local hosts ( with in ) are in following domain *.company.org So a host name will look like mymachine001.company.org Is it possible to set up wild card DNS entries of the form ? *.subd.company.com Note: The URL ends with .com, all other hosts so far ever set up in the DNS were of the format *.company.org what i am trying to achieve is the following. A user with in internal network types a url http://someprefix.subd.company.com in browser and enters. Since there is a wild card entry in DNS, the user gets routed to host mapped to *.subd.company.com in the DNS Note : at the same time, company.com has a public DNS entry and that is mapped to a physical IP in some other network (data center)
