  • VMWare ESXi virtual machine can contact the gateway but not the DNS server

    - by Nathan Palmer
    I am having a bit of a strange issue. I have a VMWare ESXi server with two virtual machines running on it. They are running just fine and can communicate on the network without a problem. I am now trying to add a third. I am installing Ubuntu 8.04 Server. I assign it a static IP address and it's a fresh installation. Once installed I can ping the gateway but I cannot ping the DNS server. It's on the same network with the other two VMs which are communicating just fine. I have tried to reinstall the operating system but it still fails to connect. Here is /etc/network/interfaces auto eth0 iface eth0 inet static address 192.168.1.23 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 208.67.222.222 #opendns dns-search mydomain.com Here is route Destination | Gateway | Genmask | Flags | Metric | Ref | Use | Iface localnet | * | 255.255.255.0 | U | 0 | 0 | 0 | eth0 default | 192.168.1.1 | 0.0.0.0 | UG | 100 | 0 | 0 | eth0 Since I'm running this behind a FortiGate this is what the sniff command gives me when I try to ping 208.67.222.222 arp who-has 192.168.1.1 tell 192.168.1.23 arp reply 192.168.1.1 is-at MAC 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request 192.168.1.23 -> 208.67.222.222: icmp: echo request As you can see it looks like I never get a response. One interesting thing I notice is the arp reply's MAC doesn't look right. I have cleared the FortiGate's ARP cache though and checked the entry and it seems correct. The MAC it lists is the one for the router. However if I ping from a different virtual machine that is also Ubuntu 8.04 with a nearly identical configuration I get this. 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply 192.168.1.22 -> 208.67.222.222: icmp: echo request 208.67.222.222 -> 192.168.1.22: icmp: echo reply So, what could I be missing? Thanks.

  • Windows server 2008 R2 error :The page file is to small to complete the action

    - by kishore
    I have a windows server 2008 R2 standard edition. The system suddenly stopped accepting remote desktop connections. When I tried to connect directly to the console, I am unable to start any applications. I got errors "The page file is to small to complete the action". Under takmanager in performance the system shows "Commit(GB) 127/127". What does this imply? The system has 32 GB ram, 5 raid disks each 150 Gb

  • Terminal Server 2008 not issuing Volume device CAL's

    - by Pieter
    We've a lot of Volume Licences left, but the License Server apparantly doesn't use them. Instead it issues Temporary Per Device CAL's. Which is a bit odd off course... There are two licensing servers installed on terminal servers, not on a domain controller (these are pushed by SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\LicenseServers registry setting) EDIT: http://img180.imageshack.us/img180/8927/ss20090909135547.png

  • SQL Server 2008 R2 cluster on Windows Server 20008 R2 issue

    - by Yousui
    I have a SQL Server 2008 R2 cluster on Windows Server 20008 R2. There are 2 nodes node1 and node2 in the cluster. When I start node1 and node2, I get the following statue information from them: From node1: C:\>cluster node Listing status for all available nodes: Node Node ID Status -------------- ------- --------------------- node1 1 Joining node2 2 Down C:\> From node2: C:\>cluster node Listing status for all available nodes: Node Node ID Status -------------- ------- --------------------- node1 1 Down node2 2 Joining C:\> I tried to use the cluster manager to investigate, but it seems it just can't connect to the cluster. How to investigate this issue? Thanks.

  • Logging in as the same user multiple times in Remote Desktop Windows Server 2008

    - by Little_Johnn
    Quick question: I have a situation where I need to let multiple people on different PCs log into one server 2008 machine as administrator simultaneously over remote desktop. I have the CALs for it, it's just not set up correctly. When one user tries to log in, it boots the other out. What I need is to present to them a different session, just each as logged in as admin. Sorry for the slightly rambling post, I'm new here. Thanks!

  • Using both IIS6 and IIS7 with the same SQL State Server

    - by Josef
    We are trying to use new IIS7 (32bit, Classic Mode) webs in addition to our IIS6 webs with one SQL State Server for ASP.NET Session Handling. Unfortunately the number of transactions per seconds in the State Servers spikes (10 times+) as soon as we add the new IIS7 web to the farm. Are there any known issues with the described setup?

  • Cannot access domain from windows 2003 client

    - by Peuge
    Hey all, First off I am a novice at AD and DNS so please bear with me. This is my current situation: I have one server which is a DC and DNS server (win2k3) - Machine 1. I have another machine which is trying to join this domain - Machine2. This machine is also a win2k3 server. This is what I have done so far: I have setup DNS on the DC and its tcp/ip dns is pointing to itself. On machine2 I have set its dns to point to the dc. The DNS has been setup with a forward lookup zone with the same name as the domain (accdirect.com). I can ping machine1 from the machine2 by its FQDN and ip. I have set up forwarders on the DC for our ISP dns and can browse the internet on both machines. In the DNS mmc on the DC I can see a host (A) has been created for machine2. The problem is I still cannot join the domain. When I try join the domain via my computer - properties then it brings up the username/password box and after I go "ok" it says cannot find domain accdirect.com If I run this from machine2 dcdiag /s:accdirect.com /u:accdirect.com\admin /p: then I get the following: Performing initial setup: ** Warning: could not confirm the identity of this server in the directory versus the names returned by DNS servers. If there are problems accessing this directory server then you may need to check that this server is correctly registered with DNS [accdirect.com] Directory Binding Error 1722: Win32 Error 1722 This may limit some of the tests that can be performed. Done gathering initial info. On the dc all dcdiag and netdiag results pass. If anyone could help me I would really appreciate this! Sorry if any of my terminology is a bit off, I have only been doing this for two days. thanks Peuge

  • Java application server behind IIS 7.5 on Windows Server 2008

    - by perissf
    I have a Java application server (GlassFish, indeed, but the problem is the same for any other application server, I guess), running on port 8080. And I have IIS 7.5 listening on port 80 as by default configuration. I want to avoid people typing the port because it's unprofessional. So I want that when somebody types http://myserver the traffic is directed to IIS. And this is how it already works now. But I also want that when somebody types http://myserver/java the traffic is directed to port 8080 and consequently my GlassFish splash screen is displayed. If I have deployed an application on GlassFish under context root app1, typing http://myserver/java/app1 should access the application. How can I do this? I have tried with adding some rules with the URL Rewrite utility from IIS7.5 UI, but this shows the port after the rule has rewritten the url, and I want to avoid it.

  • DNS failover in a two datacenter scenario

    - by wanson
    I'm trying to implement a low-cost solution for website high availability. I'm looking for the downsides of the following scenario: I have two servers with the same configuration, content, mysql replication (dual-master). They are in different datacenters - let's call them serverA and serverB. Users use serverA - serverB is more like a backup. Now, I want to use DNS failover, to switch users from serverA to serverB when serverA goes down. My idea is that I setup DNS servers (bind/powerdns) on serverA and serverB - let's call them ns1.website.com and ns2.website.com (assuming I own website.com). Then I configure my domain to use them as its nameservers. Both DNS servers will return serverA IP as my website's IP. If serverA goes down I can (either manually or automatically from serverB) change configuration of serverB's DNS, to return IP of serverB as website's IP. Of course the TTL will be low, as it's supposed to be in DNS failovers. I know that it may take some time to switch to serverB (DNS ttl, time to detect serverA failure, serverB DNS reconfiguration etc), and that some small part of users won't use serverB anyway. And I'm OK with that. But what are other downsides of such an approach? An alternative scenario is that ns1.website.com will return serverA IP as website's IP, and ns2.website.com will return serverB IP as website's IP. But AFAIK clients not always use primary nameserver and sometimes would use secondary one. So some small part of users would use serverB instead of serverA which is not quite what I'd like. Can you confirm that DNS clients behave like that and can you tell what percentage of clients would possibly use serverB instead of serverA (statistically)? This one also has the downside that when serverA goes back up, it will be automatically used as website's primary server, which is also a bad situation (cold cache, mysql replication could fail in the meantime etc). So I'm adding it only as a theoretical alternative. I was thinking about using some professional DNS failover companies but they charge for the number of DNS requests and the fees are very high (why?)

  • Server 2008 Likes to restart itself

    - by Campo
    I have a weird issue here. I notice about once a week the web server restarts itself. This would be only a minor issue if we were not planning on implementing an IP failover. I have checked the event logs. I don't see anything that indicates a reason for the restart. I need some help diagnosing the reason the server restarts. It happened last night at 5:00AM Last even in the log was 1 hour before the unexpected shutdown. Here is the Log for the shutdown event. Any help is much appreciated. I know there isn't much to go on yet. Log Name: System Source: EventLog Date: 5/5/2010 5:01:12 AM Event ID: 6008 Task Category: None Level: Error Keywords: Classic User: N/A Computer: SERVERNAME Description: The previous system shutdown at 4:56:41 AM on 5/5/2010 was unexpected.
