  • VMWare Newbie - looking for hardware recommendations and help :) [closed]

    - by Dan
    I am looking for some hardware recommendations on an upcoming virtualization project. We are a small company (80 users - 25 in site 1, 55 in site 2) currently using Windows Server 2003 - no VM servers yet. Our AD is setup where site 1 is the root domain and site 2 is a subdomain/subnet - connected by T1 and VPN for failover. The current DC's also server as file servers, print servers, AntiVirus servers. Email is in the cloud. Additionally then in site 1 we have 3 additional member servers - one running IBM Websphere for a customer specific app, one running Infor PowerLink (no real heavy load) and another that we use for Virtual Studio apps and also runs DirSync for Exchange Online. No heavy workloads on any of these machines really. We also have an AS400 box that we run ERP/CRM software on that site 2 connects to over the WAN link. In site 2 we also have a SQL machine that runs on Win2K server. Database files are not large less than 5 GB. Light to Medium workload on this machine. File servers in each site store less than 500 GB data and probably won't grow to more than 1TB in the next 5 years. I am looking to go to VMWare in both sites and virtualize all servers. What recommendations do you have for server, storage hardware? Is it safe to virtualize all of your DC's? Any help or advice would be greatly appreciated. Thanks.

  • Using Round Robin DNS on simple VPN setup

    - by dannymcc
    We have two internet connections which are load balanced to share the load between the two. We set this up after one of the internet provider proved to be less than reliable but great speed and latency wise when it is working. We'd rather utilise both connections as much as possible rather than leave one idle until the other drops out. We have a number of remote workers who occasionally need to connect via VPN from their laptops or iPads, we also have a small number of permanent LAN to LAN tunnels running from smaller branches. Originally we only had one internet connection and used one of our static IP addresses for all VPN users. Now that we have two internet connections running all of the time I am trying to make sure that the VPN is available to our team regardless of which connection drops. So my solution is to create two A records for our domain name with a value of vpn. and the two static IP addresses from each peer. Is this a sensible way of achieving this? Should I expect higher latency due to packets being lost if one peer fails and some packets still get routed to it anyway? A brief mockup of the setup I have:

  • Why am I unable to reach local network computers, but able to browse the web?

    - by Igor Zinov'yev
    I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net. I have tried all of the below and it didn't help: Rebooting; Reconnecting to the network; Forcing the dhclient to renew the IP address; Deleting and creating new connection profiles; Plugging my machine into another network outlet; Maybe it has something to do with routing, because I have tampered with routing tables the day before, but the tables seem ok to me: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vboxnet0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 Our LAN uses a D-Link DI-604 router, and it looks to me as if I am connected to the network outside the router. I can not even access its administration page. Please at least suggest what I can do to solve this. P.S. What seems strangest to me is that I can access the PC in question from outside the network by opening a port on the router. I have managed to ssh to it from outside, but I still can't ping nothing on the inside. P.P.S Today I tried reinstalling network-manager with --purge option, but it did no good. After that I created a new DCHP reservation for my PC in order to change my local IP, but that didn't change anything either. My PC is able to get a DHCP offer, but then it's unable to connect to any local computers. I am desperate.

  • I think installing PostFix solved my problem, but it seemed *too* easy

    - by Joel Marcey
    Hi, This is a followup to a serverfault post I made a while ago: http://serverfault.com/questions/21633/how-do-i-target-a-different-mail-server-depending-on-domain-with-exim (More context here too: http://forum.slicehost.com/comments.php?DiscussionID=3806 ) I have a slice/VPS at Slicehost. I basically decided to scrap exim (i.e., purge it), and start anew with my email infrastructure. In case you didn't read any of the above threads, basically my goal was to have a send only mail infrastructure that relays all outgoing email to Google Apps. I also wanted to where email from domain1 (a Wordpress installation) would show it coming from domain1.com and email from domain2 (a normal website) would show it coming from domain2.com. So I decided to give PostFix a try. I literally followed the surprisingly simple instructions here: http://sudhanshuraheja.com/2009/02/slicehost-setup-outgoing-mail-google-apps-postfix/ And voila, all seems to be working as I expected. My email tests show email coming from the proper locations (either domain1 or domain2 depending on where the emails were sent from). But this all seemed too simple to me. So simple, in fact, that I feel that something is amiss. When I installed PostFix according to the instructions in the post above and it worked, I was surprised that I didn't have to specify an SMTP server, a port number, any authentication credentials, etc. My slice is set up such that I have MX records for Google Apps (e.g., ASPMX.L.GOOGLE.COM.) in my DNS settings, but I am not sure if that is why it is working. My email infrastructure knowledge is admittedly limited, but with this am I suspect to: Spammers using my email infrastructure? My emails going to people as spam? Something else sinister? I have actually stopped running PostFix until I understand this better. Thanks!

  • Membership in two domains

    - by imagodei
    Hello! I would your suggestions for an effective solution for a person, who needs to access resources in two Windows domains and wants to use one computer. It's about our CEO, who has accepted a second position in another company. Accessing files and folders isn't big problem. The greatest challenge I see is that he wants to conveniently access Exchange accounts in both companies; he would like to send and receive mail in single Outlook if possible (two profiles?) There is also a challenge with calendars: he would like to have one calendar for all activities from both Exchange accounts. Creating a POP3 account for accessing second Exchange server is a last resort, because obviously there is a problem with scheduling meetings and other calendar related tasks. Forwarding and receiving all mail/tasks on primary Exchange server is inconvenient because simple replying to original sender is disabled; and also when manually changing the recepient, he will receive mail from the wrong address. We were considering Virtualisation, that is setting up an instance of virtual machine inside existing installation and then joining this virtual computer to a second domain. Then installing another MS Outlook. This would of course mean two different Outlook accounts, two different calendars, but would at least enable our CEO to access all information from a single laptop. Does anyone have any other idea? I know setting up two domains on a single computer is a no-go (without much hacking at least), but effective workarounds are appreciate. The thing I am looking here is high usage/efficiency/productivity, but also as elegant solution from the administration point of view. Thank you very much (if you managed to read this through, this is a good sign ^_^ )

  • Server unreachable without www

    - by deamon
    My server is unreachable without "www." prefix, even when trying it with ping. The DNS entry looks like this: $TTL 86400 @ IN SOA ns1.first-ns.de. postmaster.robot.first-ns.de.

  • Cannot Access Local Network Shares (Strange Schannel and lsass.exe issues)

  • Gmail won't forward mail sent to myself.

    - by BHare
    I own a dedicated server with a domain, we'll say foobar.com. I use google apps to manage my email SMTP servers. Now I don't check two gmail inboxes. I have my own personal one, and then I have foobar.com's inbox from google apps. Naturally the easiest thing to do is just have all foobar's emails forwarded to my personal one. So then I am only checking 1 inbox. This is all fine and dandy. I use MSMTP that with a wrapper that uses /etc/aliases. I have it set so any mail attempting to go to root (Things from cron, etc) will go to [email protected]. So when google app's (foobar.com) gets an email from the email I have setup with it ([email protected]), it automatically doesn't forward the message. This is a "feature" to gmail/google apps I suppose. How do I get around it? workarounds? etc. I could just have my alias set to my personal email but I wanted a place to have all foobar related emails archived in one place (googleapps).

  • First web server questions

    - by Graeme
    Hi there, Just looking for some help/suggestions with this. I require my own server for an upcoming project that will be hosting users websites. I want to build a control panel the user can log into and modify their website which will be stored elsewhere on the server. This all seems easy enough, It's just managing domains and emails that confuse me. What should I look for to manage domain names and point them to the correct website and also what would be the best way to manage email accounts/set up new ones etc. I want to avoid cPanel/WHM if possible, I'm looking to control most things through the control panel I will be building. So any suggestions on this would be useful as well, as I will be wanting to add email accounts through php (Can be done using a shell I assume?). I will also be wanting to measure bandwidth used on the websites contained in each users directory, any suggestions on making this possible? I'm really looking for some suggestions on what software to use to set this up, any advice would be really helpful! Thanks, Graeme

  • Network Security Device/Software

    - by Campo
    We currently run Symantec Antivirus Corporate 10.2. The software is really easy to manage on a network but the actual virus detection isn't bad but the malware detection is crap. We recently were infected with a email bot that got us put on some block lists. This has been resolved. I cannot have that happen again. I would like to find a program as easy to manage as symantec that I can install on all the user's workstations as well as the servers. We run a windows 2003 domain. We have a couple 2008 test servers in the environment. Most of the workstations are xp though I am using windows 7 and symantect is not compatible with this OS... So we need a solution that would cover all those operating systems. If it could be installed on macs too that would be a bonus though not necessary at all. This software must detect: Viruses AND Malware I am looking for something that combines the features in anti-malware programs like malwarebytes or spybot with an antivirus program like symantec or AVG. Alternatively if there is a piece of hardware that is a firewall, router, and packet inspection for virus/spam that would be the most ideal solution. I then could supplement with a piece of software that could pickup what the hardware misses. Thank you for your suggestions.

  • Am I able to forward traffic from an external subdomain to a specific local host?

    - by George Bowman
    I apologise in advance if the question doesn't make sense, please let me know. I've got a small LAN (~10 Virtual Servers) using Win Server 2008 as a DNS server. This is behind a smoothwall express 3.0 firewall with ports forwarded for specific services. I have a domain (123-reg) with the NS's that of afraid.org (DynamicDNS) and subdomains pointed to my (Dynamic) IP address e.g. subdomain1.example.com - 123.456.789.101. I think that adequately explains my set up. My question is, am I able to have subdomains e.g. subdomain1.example.com only point to a specific local host? Like so: subdomain1.example.com:80 - firewall(external facing) - server1.example.com:80 subdomain2.example.com:80 - firewall(external facing) - server2.example.com:80 I don't actually necessarily want to use port 80, otherwise I would just use VirtualHosts on apache, it is just an example port. Currently I can use either subdomain1.example.com OR subdomain2.example.com and they will both point to server1.example.com:80 I do not have to stay using Win Server 2008 for DNS, I am more than happy to move over to BIND if needs be, it was just easier to use Win Server 2008's DNS. I do not know if this is even possible, I have a feeling it isn't as I've only got one external IP address but any information is useful!

  • 2 Web Servers, 2 Domains, 1 WAN IP configuration

    - by Tillman32
    The Problem: I have 2 domains, 2 web servers, 1 WAN IP. This is on a home network, so I don't have any crazy router or anything with the right tools, at least I don't think I do. I have a Dlink DIR-655 router. I need to be able to forward the website to the right box. 1 server is hosting www.site1.com, and the other should be hosting, www.site2.com. I forwarded the domain, to a port that is forwarded to that box. wanip:1235, 1235 is then forwarded to the internal IP of site2's server. But when I go to www.site2.com I get the 404 page of www.site1.com. I need www.site2.com to go to the right server. Is this something I can do in the virtual hosts of www.site1.com or is it something else. Also, if this isn't entirely possible, or if its a big process, I can just move www.site1.com to the www.site2.com's server, and use virtual hosts, that is an option that I would be okay with.

  • A duplicate name has been detected on the TCP network

    - by MSedm
    When I installed my domain controller and DNS, I had 2 NIC on the server. Both NIC has its own IP address. NICs are not teamed, they are seperate and ip address are in the same subnet. Both IP address are now registered in the DNS. i found them in Forward and reverse lookup zone. Everything working ok except the following error in the event log. "A duplicate name has been detected on the TCP network......" Now I have realized that this is because of the second NIC. My question is if i disable the second NIC, what happen to those DNS record assiciated with the second ip address? How do I remove all the DNS recored for the disabled NIC? There are A record, some record with the name (same as parent folder), PTR record and may be more. How do i disable second NIC and remove all the associated DNS recoreds? Please help.

  • Old network login passed to IIS

    - by 300 baud
    Let me start by saying that I am not a server guy - I am a developer. But I develop and manage an ASP.NET application that uses Windows authentication. I've run into the problem I am about to describe before, and I would just like to understand how to remedy it since I am the one who always gets the original support request. A user, let's call her JaneDoe, has just gotten married and her login has been changed to JaneJones. We have an application that uses Windows authentication to store the user's login name to a table and then redirects the user to another non-Windows authenticated site with a GUID which points to the table entry we just made. When the user reaches the second site, we read in the login name from the database using the GUID that was passed. Then, we look up the login name in another database where we track application permissions. The problem is that the user is logging into her workstation as JaneJones, but the Windows authenticated site is still receiving a login name of JaneDoe. Is this a domain controller issue? Is it a workstation issue? What's the best way to resolve this?

  • Time sync fails on Hyper-V VM, but succeeds when I log in as a domain user

    - by Richard Beier
    We have a Windows Server 2003 SP2 VM running on Hyper-V (Server 2008 R2 host). The VM has Hyper-V time synchronization enabled. I noticed that the time on the VM was fast by around 25 minutes. I saw the following in the event log: The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible. No attempt to contact a source will be made for 15 minutes. NtpClient has no source of accurate time. The time provider NtpClient cannot reach or is currently receiving invalid time data from ourdc.ourdomain.local (ntp.d|192.168.2.18:123-192.168.2.2:123). Time Provider NtpClient: No valid response has been received from domain controller ourdc.ourdomain.local after 8 attempts to contact it. This domain controller will be discarded as a time source and NtpClient will attempt to discover a new domain controller from which to synchronize. I had been logged in as a local user. (We have an old app that runs on this VM - it requires a user to be logged in at all times, and we use a non-domain user account for this.) When I logged in as a domain user, the clock almost immediately corrected itself. Running "w32tm /monitor" and "net time" as the domain user showed no errors, and indicated that our domain controller was the time source. Does anyone know what might cause this, and why logging in under a domain account fixes the problem? I'm wondering if the time will start to drift again. Thanks for your help, Richard

  • Only one domain is not resolving via Windows DNS server at multiple locations, but is at others

    - by Brett G
    I'm having quite a weird issue. Had mail delivery issues to a specific domain. After looking closer, I realized that the DNS for that domain isn't resolving via the in-house Windows 2003 SP2 DNS server. C:\>nslookup foodmix.net Server: DC.DOMAIN.com Address: 10.1.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DC.DOMAIN.com timed-out (DC.DOMAIN.com and 10.1.1.1 are generic values to replace the actual ones) Even if I run this nslookup from the DC.DOMAIN.com server, I get the same result. However, all other requests are working as they should. I had a sysadmin friend try this DNS lookup on servers at several companies that he consults for (which are also Windows 2003 AD servers). The weird thing is some of these were having the same exact issue. However using public DNS servers work. I have tried clearing the DNS cache, restarting the server, restarting the services, etc. Nothing has worked. One weird event I noticed in the DNS Server Event Logs that might be related is an event ID of 5504 with the following description: The DNS server encountered an invalid domain name in a packet from 192.33.4.12. The packet will be rejected. The event data contains the DNS packet. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. In the data section below, I can see the following mentioned: ns2.webhostingstar.com Which happens to be the nameserver for the domain in question. Several discussion threads and a MS KB have pointed to disabling EDNS. I have done this via "dnscmd /config /enableednsprobes 0" and it has not fixed the issue.

  • Silverlight and clientaccesspolicy.xml

    - by JerA
    I have a silverlight app hosted on "dev.system-engine.com" which creates an tcp connection connecting to "dev.system-engine.com" the silverlight app and the policy file are on the "dev.system-engine.com" webserver. "system-engine.com" and "dev.system-engine.com" are separate servers. I cannot seem to get it to work. I have been struggling with the policyfile. <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from> <domain uri="http://dev.system-engine.com:80"/> </allow-from> <grant-to> <domain uri="http://dev.system-engine.com:80"/> <socket-resource port="80" protocol="tcp"/> <resource path="/" include-subpaths="true"/> </grant-to> </policy>

  • .NET Membership with Repository Pattern

    - by Zac
    My team is in the process of designing a domain model which will hide various different data sources behind a unified repository abstraction. One of the main drivers for this approach is the very high probability that these data sources will undergo significant change in the near future and we don't want to be re-writing business logic when this happens. One data source will be our membership database which was originally implemented using the default ASP.Net Membership Provider. The membership provider is tied to the System.Web.Security namespace but we have a design guideline requiring that our domain model layer is not dependent upon System.Web (or any other implementation/environment dependency) as it will be consumed in different environments - nor do we want our websites directly communicating with databases. I am considering what would be a good approach to reconciling the MembershipProvider approach with our abstracted n-tier architecture. My initial feeling is that we could create a "DomainMembershipProvider" which interacts with the domain model and then implement objects in the model which deal with the repository and handle validation/business logic. The repository would then implement data access using our (as-yet undecided) ORM/data access tool. Are there are any glaring holes in this approach - I haven't worked closely with the MembershipProvider class so may well be missing something. Alternatively, is there an approach that you think will better serve the requirements I described above? Thanks in advance for your thoughts and advice. Regards, Zac

  • Is Form validation and Business validation too much?

    - by Robert Cabri
    I've got this question about form validation and business validation. I see a lot of frameworks that use some sort of form validation library. You submit some values and the library validates the values from the form. If not ok it will show some errors on you screen. If all goes to plan the values will be set into domain objects. Here the values will be or, better said, should validated (again). Most likely the same validation in the validation library. I know 2 PHP frameworks having this kind of construction Zend/Kohana. When I look at programming and some principles like Don't Repeat Yourself (DRY) and single responsibility principle (SRP) this isn't a good way. As you can see it validates twice. Why not create domain objects that do the actual validation. Example: Form with username and email form is submitted. Values of the username field and the email field will be populated in 2 different Domain objects: Username and Email class Username {} class Email {} These objects validate their data and if not valid throw an exception. Do you agree? What do you think about this aproach? Is there a better way to implement validations? I'm confused about a lot of frameworks/developers handling this stuff. Are they all wrong or am I missing a point? Edit: I know there should also be client side kind of validation. This is a different ballgame in my Opinion. If You have some comments on this and a way to deal with this kind of stuff, please provide.

  • How do browser cookie domains work?

    - by Vilx-
    Due to weird domain/subdomain cookie issues that I'm getting, I'd like to know how browsers handle cookies. If they do it in different ways, it would also be nice to know the differences. In other words - when a browser receives a cookie, that cookie MAY have a domain and a path attached to it. Or not, in which case the browser probably substitutes some defaults for them. Question 1: what are they? Later, when the browser is about to make a request, it checks its cookies and filters out the ones it should send for that request. It does so by matching them against the requests path and domain. Question 2: what are the matching rules? Added: The reason I'm asking this is because I'm interested in some edge cases. Like: Will a cookie for .example.com be available for www.example.com? Will a cookie for .example.com be available for example.com? Will a cookie for example.com be available for www.example.com? Will a cookie for example.com be available for anotherexample.com? Will www.example.com be able to set cookie for example.com? Will www.example.com be able to set cookie for www2.example.com? Will www.example.com be able to set cookie for .com? Etc. Added 2: Also, could someone suggest how I should set a cookie so that: It can be set by either www.example.com or example.com; It is accessible by both www.example.com and example.com.

  • How to add a local file to trusted zone in IE8?

    - by Raghu Dodda
    I want to add a file on my local drive (C:\something.html) to the Trusted Zone in IE8 (my OS is Windows Server 2003). The Add Sites Dialog box, does not seem to take entries for files on the local drive. I have tried: file://C:\something.html file:\\localhost\c$\something.html I have seen other solutions (on superuser and elsewhere) such Mark of Web, that allow your local file to be treated as if it were part of the internet zone, but I want to add my file to the Trusted Zone. How can I do this? Thanks.
