  1. From what I know, is not possibile to connect via RDP and hide the name... ok... you may be victim of a MITM RDP but if so, your session will be disconnected. Write down the "strange" IPs and PM me. Also, when you notice this, open a command prompt and type: netstat -an |find /i ":3389" so you can see all the RDP connection opened. Remember that RDP is not a lightweight protocol!
  2. Mhhh not sure... but... on HP switches, when you make a configuration, you MUST SAVE IT in another page. If you don't do this, when you unplug / restart the switch, everything turns back to the old settings... If this doesn't help, open a topic on D-link support site.
  3. Mhhh I think this is a good list. Just one point more: a domain controller should be a domain controller. Not a DC and web server! Better for security AND performances!
  4. Hi, When you say: " I want that all the users on the network should get equal speed nobody gets more", does it mean that if you have 1 MB line, and 10 users, each user must use only 100 KB/s also when there's more available? This cannot be done via Windows Server. Regarding dhcp, basically if the DHCP find a mac address already in its list, it simply tries to RENEW it, so it's already done by DHCP mechanism. But you cannot force the assignment... well... you could create scopes, but actually is not a great idea create a scope for each computer -.- Regarding load balancing, you can take a look at NLB (network load balancing) but it works with clusters.
  5. I'm not english mother language too, what's your mother language?
  6. Check in your FORWARDERS that you don't have the old server. Also make sure that FORWARDERS are the addresses provided by your ISP.
  7. Yes, you can disable DNS on your router... but it doesn't matter, because if you set the clients to point on your server, they will never know anything about your router :)
  8. Just to isolate your problem: Set the DNS on ONE client to 8.8.8.8, then type ipconfig /flushdns Retry, do you have the same issue?
  9. Hi, You could consider XenServer from citrix which is free (with some limitation). Anyway, Hyper-v is the "program" to virtualize VMs, SCVMM is more something to manage many VMs spread on your network and also to monitor clouding services and so on. Basically I think this is the main difference.
  10. You can use this: http://www.mp3vcr.com/sharemonitor/ But I'm not sure it will work on Server 2k8. You can always enable auditing: 1. Go to Control Panel > Administrative Tools > Local Security Policy. 2. Security Settings > Local Policies > Audit Policy. 3. Audit object access and check the Success checkbox. 4. Select your folder, go to Security tab, click Advanced button, go to Auditing tab and click Add button. Enter EVERYONE as object name and click OK Now select what you want. Then, to discover WHO is modifying things, go to event viewer > security. Pls, let me know who is the guilty :P
  11. Stupid thing... but... try: uninstall the FRAMEWORK and reinstall it. Printer redirection is involved in the process. Also, check your TS when the user log on for errors or warning. ALso check when he prints if there's something...
  12. Hi, First, what does it mean? Windows can work on a stand alone server... Regarding all your questions, I really suggest you to read this article, it explains WHERE you can put a public DNS. http://www.isaserver.org/tutorials/how_to_publish_a_dns_server_part_1__the_pathophysiology_of_the_same_internal_andexternal_domain_name.html If you have other questions, feel free to ask!
  13. Yes, you're right. First you must renew the cert, then, renew from server. Can't you simply contact the issuer and explain your situation?
  14. VSS does not change date. But Backup can. What program are you using to backup? What type of backup are you using? Can you say that this happens only on backed-up folderds but not on "unsaved" folders?
  15. So I think your problem is the private key, in some way Windows cannot find it anymore and so cannot associate the pair. I found this article, http://technet.microsoft.com/en-us/library/dd362655.aspx but it is useless because you need the GUI in order to proceed. No idea, sorry.
  16. Try to change port, use a port < 22 Most of switches don't permit to use port 23,24 and 25,26 togheter.
  17. Hi, DNS RESOLVES name to IP and vice versa. if you try to ping www.google.com you receive this message: Pinging [url="http://www.l.google.com"]www.l.google.com[/url] [74.125.39.99] with 32 bytes of data: Reply from 74.125.39.99: bytes=32 time=30ms TTL=53 Can you see the IP? Internet works with IPs not with names, but for us (people) it's easier to remember name instead of numbers, right? There are 13 ROOTs DNS server which are there to answer the questions. How it's made a question? Easy: Let's say you want to navigate to www.serverforum.org. PLEASE NOT THE DOT AT THE END! The query is splitted: www windows2008forum com . Starting from the right or from the bottom, you have .[dot] this is managed by ROOT DOMAINS NAME SERVERS. They look at the next part: COM and they say: HEY, I know WHO is responsible for COM domains, let's forward the query to WHO MANAGES "COM" domains. So, the manager of COM domains check the next part WINDOWS2008FORUM and says: "Hey, I have something which is called WINDOWS2008FORUM" and it forwards the request again. Finally the WWW HOST is searched and... FOUND! So, you have the main page of your site! What a DNS server does is to resolve name on ip and vice versa. Fist of all you must configure a DNS service on your service, once ready, change DHCP options to point on another DNS server. Actually if you don't need specials configurations (like AD or web site hosting), you router is doing the right job, so you don't need another server. There are many other possibilities, like virtual hosting, aliases, records, trees and so on, but basically this is what you need to start with DNS server which is not really the easier thing in a network. Many problems with AD are caused by misconfigured DNS.
  18. You can't, but you really should install another VM... trust me.
  19. Are you sure this is correct? /DN DC=DC=Test,dc=local It should be: /DN DC=Test,dc=local Maybe I'm wrong... but this is my only idea.
  20. 1) Update existing WS to Windows 7 > others WS (I don't know how many) with the following hardware: 4 GB ram Core i3 / i5 or AMD X3 500 GB hd A workstation should cost about 700$ with monitor, HP is ok. 2) 6 groups: dir, sec, tea, lib, comp lab, students. If you want you can create multiple under-groups for students (class 1, 2, ...). 3) Most used and with Windows clients, it's the best integration. 4) It's not specified if the attack is from outside or inside, anyway, block the ZONE TRANSFER on DNS. 5) 8]1. Stupid question: why I can't host a DC? If I delegate a control (which is the only solution), the problem on questione #4 persist... 8]2. Once again... you can specify how many times the zone transfer succede but actually I should implement a DC in Toronto... 6) 8]1. WINS server? Why should I have enabled WINS? Anyway I don't understand the question: "AT WHAT LEVEL SHOULD YOU CONFIGURE THE DHCP OPTIONS?" er... Where the DHCP is made?! On Windows server? So, in windows server... 8]2. Using scopes or address pools with rules, once again... WHO IS PROVIDING DHCP?! 7) 8].1 It downloads the updates ONCE and the DEPLOY to the network, clients must be configured (via GP) to point to WSUS server. 8].2 1 server should be ok, updates can be done during the night and with policies you can divide updates. What I mean is: monday: update STUDENTS CLIENTS (AD Group), thusday TEACHERS CLIENTS, and so on. 8].3 Once installed, there are many options and one is called: "AUTO APPROVE AND INSTALL" 8) 8].1 Best thing is to use a SNMP monitor, enable SNMP on clients and install a software to monitor (SYSAID is free, take a look!) 8].2 Any, you just need SNMP which is compatible with almost any OS. 9) 8].1 Depending on where you want to save data. ANyway, first of all buy an INTERNAL RAID CONTROLLER and set up a RAID 5 (at least 3 internal disks). Then buy an external NAS and there you can backup. Another (but more expensive) solution is a SCSI drive, external. Faster but REALLY expensive. 8].2 With a RAID 5 you can easily replace the faulty disk and everything is restored without downtime. You can also use Acronis or Ghost to perform a system image. 8].3 Yes, Acronis or Ghost can restore a single file. Only from RAID YOU CANNOT RESTORE A FILE.
  21. Help... means that you don't understand something OR it means that you want all the answers to all questions? I think that the 90% of questions are really really easy... the other 10% it's a bit harder but just because you need to be familiar with some concepts (like question 4, it talks about zone transfers). So, let us know what do you really need.
  22. What are the differences between this and the others clients? I mean, something must be different!
  23. So DO NOT IMPLEMENT the same DC for both inside and outside. Use a RODC!
  24. I think so, well, in theory the most restrictive count... so I assume you're right, but I will ask in the next few days.
  25. Wait, this is correct based on what do your want to do... On your LOCAL (PRIVATE) network, your DNS works like a charm, outside it's different. You DC is not published on internet, so you CANNOT ping it. For security purpose I don't suggest you to put the same DC also over the internet, instead use a RODC (Read only domain controller). But do you really need an external domain controller? If yes, be sure to set up a RODC OUTSIDE your LAN (in another VLAN or something like this).
