• Cisco SA520 to Adtran 1234 no DHCP transfer

  - by Grico

  I am trying to set up a Cisco SA520 to run DHCP on my network. I have a vendor provided switch, the Adtran 1234, and it provides DHCP for our phone systems on VLAN 200. I do not have access to the Adtran, but the vendor gave me a IP on port 1 for WAN and said port 2 should be for the "trust" side should go. I did setup a mini lab where, Adtran 1 went to SA520 WAN port, and SA520 trust 1 went to my laptop. Everything worked fine, I could ping and get internet using the DHCP scope I put on the SA520. I then unplugged my computer from SA520 trust 1 and plugged it into Adtran 2. I plugged my computer into Adtran 23 and I dont get DHCP or even a link light. If I restart my machine, I get a brief link and then it dies once the machine boots. I have tried several ports on the Adtran and none seem to work. Different cables as well. However, when I plug a phone into the Adtran, the phone boot immediately and shows link. Thoughts?

• Time not propagating to machines on Windows domain

  - by rbeier

  We have a two-domain Active Directory forest: ourcompany.com at the root, and prod.ourcompany.com for production servers. Time is propagating properly through the root domain, but servers in the child domain are unable to sync via NTP. So the time on these servers is starting to drift, since they're relying only on the hardware clock. WHen I type "net time" on one of the production servers, I get the following error: Could not locate a time-server. More help is available by typing NET HELPMSG 3912. When I type "w32tm /resync", i get the following: Sending resync command to local computer The computer did not resync because no time data was available. "w32tm /query /source" shows the following: Free-running System Clock We have three domain controllers in the prod.ourcompany.com subdomain (overkill, but the result of a migration - we haven't gotten rid of one of the old ones yet.) To complicate matters, the domain controllers are all virtualized, running on two different physical hosts. But the time on the domain controllers themselves is accurate - the servers that aren't DCs are the ones having problems. Two of the DCs are running Server 2003, including the PDC emulator. The third DC is running Server 2008. (I could move the PDC emulator role to the 2008 machine if that would help.) The non-DC servers are all running Server 2008. All other Active Directory functionality works fine in the production domain - we're only seeing problems with NTP. I can manually sync each machine to the time source (the PDC emulator) by doing the following: net time \\dc1.prod.ourcompany.com /set /y But this is just a one-off, and it doesn't cause automated time syncing to start working. I guess I could create a scheduled task which runs the above command periodically, but I'm hoping there's a better way. Does anyone have any ideas as to why this isn't working, and what we can do to fix it? Thanks for your help, Richard

• Windows 2008 R2 remote desktop - Double Login

  - by Zulgrib

  After an Active Directory fail RDP connection started to ask for credentials twice (once on local RDP program, second time on remote's logon screen) I already looked at Windows 2008 R2 RDS - Double Login Solution provided there doesn't work for me. The server is alone, without AD/DNS services, RDP service isn't installed I tried every security settings on RDP-Tcp (RDP, Negotiate, SLL) Logon option is set to "Use credentials from the client" Both windows client and server use RDP 7.1 fPromptForPassword regitries are set to 0 Local Computer Policy\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Security\Always prompt for password upon connection is set to "Disabled" Why i am sure the problem comes from the server and not the client ? This problem affected a 3rd RDP program on Android too (it was directly showing "preparing desktop previously, on both MS RDP and the 3rd program) No bakcup are available (Else the Active Directory wouldn't be a fail, but just a lose of time) I am wondering if a rule linked to RDP got changed after the AD install+unistall, but i'm unable to find where. While this is not a critic problem, this is very annoying. I don't know if more information are needed, if it's the case and if you are patient enough, please tell me what is missing and i'll edit this post to add the missing informations.

• Mac Port error installing gsoap

• Can't connect to a Hyper-V VM from anywhere but the host OS

  - by Elbelcho

  I have an unusual situation on hand where I'm able to connect to a Hyper-V guest VM from the HOST, but not from anywhere but the host. The VM is running WIn2k8R2 and has IIS installed and Remote Desktop enabled. If I browse to the IP from the host OS, the IIS7 page displays. I can also RDP into the guest OS from the host as well as ping. From OFF the host, RDP, web and ping all fail. If I completely shut off the guest VM's firewall, ping will then start to respond, but all RDP and port 80 still don't. The physical host machine has 2 nics installed, but only one is plugged in. The one plugged in has a static IP. I have one Hyper-V virtual network and it's set to external. The guest VM has one NIC with a different static IP than the host, but both are on the same subnet. The host machine is joined to the domain, the guest VM is not. Any sugestions? Thanks so much for any help you may be able to provide!

• Cent OS ifcfg configuration for ranges of IP's with different netmask

  - by Aaron Schlegel

  I have 1 set of 30 public IP's with a netmask of 255.255.255.0 and another set of 30 IP's with a netmask of 255.255.255.128. Both sets of IP's also have different gateways. How can I virtually assign the IP's to the machine? I have tried creating ifcfg-eth0:0 ifcfg-eth0:1 ifcfg-eth0:X ect for each IP. Below is my ifcfg file with. I have this for each IP with the correct gateway IP and netmask for each of my 60 IP's. If I do ip addr show it does show all of the 60 addresses with the correct broadcast IP and netmask. However I can only use 30 of my IP's that are from the same netmask. Am I doing this correctly? If the IP's show up with ip addr show does that mean I have correctly assigned them to the machine virtually? I want to check before I blame my hosting company for not routing the IP's correctly. DEVICE="eth0:1" BOOTPROTO="static" DNS1="**.**.**.**" DNS2="**.**.**.**" GATEWAY="2**.**.***.126" HOSTNAME="localhost.localdomain" HWADDR="0*:19:**:**:**:**" IPADDR="2**.*.**.**" IPV6INIT="no" MTU="1500" NETMASK="255.255.255.128" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" Also is there a better way to do this? I have used ifcfg-eth0:0-range1 before to assign a range of IP's from the same netmask. Is it possible to do this with ranges with different netmask? Thanks!

• Windows 7 on an EEE PC 901 - Is it a practical change?

  - by Dave

  I am currently running WinXP on my EEE PC 901, and I'm happy to say that it runs really well. But this did not come with out significant manipulation of the OS. Here's the basic steps I took: Install XP Modify registry to install Install bare essential drivers Relocate page file to d:\ (remember, this model has two SSD's, one roughly 3.6gb, and the other roughly 16gb - XP won't run on the bigger drive, only the smaller one) Install remaining drivers skip normal updates, install service pack 2 straight away. modify system registry to place service pack backup folder into new Program Files directory on D drive (where software is being installed). Change My Documents folder to sit on D drive. Install .net framework Install remaining updates and service pack 3 (the hidden backup folders in the c:\Windows directory are deleted after every update as well as the contents of the service pack downloads folder in order to continually free up space). I have also found that Disktrix UltimateDefrag to be brilliant at keeping the system clean and tidy. This is roughly the order I did things in. In this configuration the machine works really well. QUESTION: Can this kind of configuration be implemented with Windows 7 to achieve the same result on this machine? Thanks in advance. Dave.

• Squid - Active Directory - permissions based on Nodes rather than Groups

  - by Genboy

  Hi, I have squid running on a gateway machine & I am trying to integrate it with Active Directory for authentication & also for giving different browsing permissions for different users. 1) /usr/lib/squid/ldap_auth -b OU=my,DC=company,DC=com -h ldapserver -f sAMAccountName=%s -D "CN=myadmin,OU=Unrestricted Users,OU=my,DC=company,DC=com" -w mypwd 2) /usr/lib/squid/squid_ldap_group -b "OU=my,DC=company,DC=com" -f "(&(sAMAccountName=%u)(memberOf=cn=%g,cn=users,dc=company,dc=com))" -h ldapserver -D "CN=myadmin,OU=Unrestricted Users,OU=my,DC=company,DC=com" -w zxcv Using the first command above, I am able to authenticate users. Using the second command above, I am able to figure out if a user belongs to a particular active directory group. So I should be able to set ACL's based on groups. However, my customer's AD setup is such that he has users arranged in different Nodes. For eg. He has users setup in the following way cn=usr1,ou=Lev1,ou=Users,ou=my,ou=company,ou=com cn=usr2,ou=Lev2,ou=Users,ou=my,ou=company,ou=com cn=usr3,ou=Lev3,ou=Users,ou=my,ou=company,ou=com etc. So, he wants that I have different permissions based on whether a user belongs to Lev1 or Lev2 or Lev3 nodes. Note that these aren't groups, but nodes. Is there a way to do this with squid? My squid is running on a debian machine.

• For Australian audiences, would an uncached .com.au domain resolve faster than an uncached .com?

  - by thomasrutter

  Is there any speed benefit to using a .com.au domain rather than a .com if your customers, hosting and DNS services are in Australia, specifically in the worst typical case (domain is not cached in any local DNS relay for customer)? Assuming that both domains pointed to the same nameservers in the end. I know this is mostly academic because we are talking about a DNS lookup that would take at most a few hundred milliseconds and would only be relevant once at the beginning of a session. I just was curious. I know that an uncached .com lookup will involve consulting at least one ?.gtld-servers.net. server and an uncached .com.au will involve consulting at least one ?.au. server. Now, what I guess I'd need to know is Are the various ?.gtld-servers.net. servers using anycast technology that would have local fully authoritative nodes in Australia, making them just as fast to Australians as ?.au. and avoiding a 200ms+ overseas latency, or are some or all of them hosted only in the US or in the northern hemisphere?

• Rename a Network Printer win Win 7

  - by Alex

  Seems this is a common question but the answers regularly miss the point. I have a server. Server has some printers connected. Server has all drivers for x32 & x64 OS PLUS ALL DEFAULTS set. Server also manages print queue. I have many workstations, all need to use the printers. All NEED to have drivers print queue and DEFAULTS propagated from server. Now.... When I add the printers on the workstations, I get: "ABC Printer on SERVER123" I need something less long - just "ABC Printer" So how? Tip: Please don't show me how to change the name of your locally installed printer. I know how to do this - I am particularly interested in shared printers that look like "ABC Printer on SERVER123" Tip: Installing the driver with a local port wont cut it because then I loose the server propagated defaults, the driver updates and I need to run around with driver disks/confuse trembling users with hard things like choosing drivers. I am happy for a hack if there is no official way to do this in the group policy.... I tried looking in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers on the workstation machines but those are only local printers :( I can see the network printer details on the workstations here: HKEY_USERS[Some GUID]\Printers\Connections But there is nothing obvious like a description string... Can anyone help with this?

• Sync desktop Mac environment to laptop

  - by Andrew Vit

  I spend the majority of my time working at my desktop Mac, which I have configured for my web development environment. My spouse has a MacBook for casual use, and I occasionally steal it back when I need to work off-site, or when travelling. The question is how to best synchronize the two so I can switch between them more readily. I've solved a few obvious things by using online services: Email is hosted on IMAP. Working files are in Dropbox. Source code is managed in git. However, the following are things I always miss when jumping on the laptop: Installed Applications (current versions) Installed libraries & utilities (/usr/local) Apache VirtualHosts & other configurations (/etc) Disk image files for VMs My current method is to connect the MacBook via Firewire target mode and rsync the /Users/me home directory, and then cherry-pick the other items I need from Applications, /etc and /usr/local. The problem with this method is that it can be very time consuming due to things like my virtual machine image files, cached emails, etc. How can I make this faster & easier? Can you recommend a solution for configuration management (so I can repeatably install & configure the same software on both), or synchronization (so I can bring the MacBook up to date nightly, over our home network)?

• Setting up Squid -> VPN connection

  - by Nedlinin

  I recently purchased a VPS and am wanting to use it as a VPN server. However, it has bandwidth limitations. So, I figured since I already have a local Squid proxy caching things for me, I could have users connect to the proxy and the proxy connect to the VPN. Then when someone hits the web, Squid will serve it from cache if available and, if not, it will use the VPN to download it. My issue is, I have no idea how to set this up :p - Essentially I want Machine - Squid - VPN. My VPN is running on Ubuntu Server with pptpd. Squid is running on a local Arch Linux box. Squid and the VPN are both working perfectly independently. Any help on how to have Squid push traffic through the VPN would be greatly appreciated! Also: I don't actually want to use the VPN for all traffic. Otherwise, I'd just connect my router to the VPN and be happy. I only want to use it for web traffic from specific machines on the network.

• Unable to connect remotely to Vsftpd server set up on CentOS VirtualBox

  - by ryekayo

  I have set up a Vsftp server using the following instructions provided Here and even went as far as following the commentary at the bottom. But I am unable to connect remotely. When I attempt to use FileZilla or my Ubuntu terminal, I always get: ryan@ryan-Galago-UltraPro:~$ ftp 10.0.x.xx ftp: connect: Connection timed out ftp> I have checked and re-checked iptables conf file and made sure that Port 21 is being Accepted and it is. I have looked this up on the web and decided to try nmap to port scan it and this is what I get for a result: ryan@ryan-Galago-UltraPro:~$ nmap -PN 10.0.xx.xx Starting Nmap 6.40 ( http://nmap.org ) at 2014-08-19 15:01 EDT Nmap scan report for 10.0.xx.xx Host is up. All 1000 scanned ports on 10.0.xx.xx are filtered Nmap done: 1 IP address (1 host up) scanned in 201.38 seconds Is there anything else that I should do or check for? UPDATE: I have tried to ping from the virtual machine to my IP address on Ubuntu and have been successfully able to. I cannot ping to my virtual machine from Ubuntu. I have narrowed this down to possibly being a firewall related issue on Ubuntu's side, but why would I be unable to connect from FileZilla?

• Problems with ipsec betwen Cisco ASA 5505 and Juniper ssg5

  I am trying to set up an ipsec tunnel between our ASA 5505 and a Juniper ssg5. The tunnel is up and running, but I cannot get any data through it.

• How can I get the root account to generate an acceptable ssh key?

  - by Jamie

  On an ubuntu machine I did the following: ~$ sudo su - [sudo] password for jamie: root@mydomain:~# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 12:34:56:78:9a:bc:de:f0:12:34:56:78:9a:bc:de:f0 [email protected] The key's randomart image is: +--[ RSA 2048]----+ | | | | | | | | | | | | | | | | | | +-----------------+ root@mydomain:~# cat /root/.ssh/id_rsa.pub | ssh -p 443 [email protected] 'cat > authorized_keys' [email protected]'s password: root@mydomain:~# ssh -p 443 [email protected] [email protected]'s password: It's asking me for a password. However, using a regular account, the following works: $ cd ; ssh-keygen -t rsa ; cat ~/.ssh/id_rsa.pub | ssh [email protected] 'cat >> ~/.ssh/authorized_keys' $ ssh [email protected] Last login: Thu Oct 24 14:48:41 2013 from 173.45.232.105 [[email protected] ~]$ Which leads me to believe it's not an issue of authorized_keys versus authorized_keys2 or permissions. Why does the 'root' account accessing the remote 'jamie' account not work? The remote machine is CentOS if that's relevant.

• Windows 7 deployment thru WDS

  - by vn

  Hello, I am deploying new systems on my network and I built my reference computer by installing the OS the manufacturers (Dell and a custom built system from some local business) gave with all drivers, installed all the desired applications. As for the settings part, I'm doing most of it thru GPOs. I want to image my reference computer and deploy it with WDS. i found several links on how to sysprep, but they're all doing it with some differences without explaining them. My questions : How do I manage (into sysprep) the domain join/computer naming part since (from what I understand) WDS manages that? How do I know/determine what I need to setup into my sysprep.xml? Can you sysprep a first time, try and if it fails, do some modifications and try again? I am thinking of doing a basis sysprep, checking what info can be automated and correct that in the answer file. What do I miss if skipping the "audit" mode? I don't plan on re-doing the reference computer... I read that when sysprepping, it resets settings from the reference computer like the computer name, activation/key and such... what setting is sysprep resetting by default that I should be aware of? I must admit I am quite lost about Win7, sysprep, RIS, MDI toolkit, WDS.. I understand the way of doing with XP, but it changed so much with Windows 7! The links I am reading are : http://far2paranoid.wordpress.com/2007/12/05/prep-for-sysprep/ http://blog.brianleejackson.com/sysprep-a-windows-7-machine-%E2%80%93-start-to-finish-v2 http://www.ehow.com/print/how_5392616_sysprep-machine-start-finish-v2.html Thank you VERY much for any answers, they are much appreciated.

• Plesk 10 - creating and using vhost.conf

  - by MrFidge

  I'm having some issues setting up and using a vhost.conf for one of my domains. So far none of the domains have required any extra configuration but now I need to use a PEAR module, so I'm looking to include /usr/share/pear in the PHP settings for the domain. vhost file created in /var/www/vhosts/domain.com/conf/vhost.conf <Directory /var/www/vhosts/domain.com/httpdocs> php_admin_value include_path ".:/usr/share/pear" </Directory> I then restart Plesk using: /usr/local/psa/admin/sbin/websrvmng --reconfigure-vhost --vhost-name=domain.com Or as plesk says that command is obsolete in Plesk 10 I've tried using /usr/local/psa/admin/sbin/httpdmng --reconfigure-domain domain.com And for good luck I've restarted apache too each time. Net result - none of the PEAR includes work unless I edit the include_path in /etc/php.ini! Any tips on how to get this MOFO working? I've had a look through the documentation but TBH I just don't have time to read 40 pages of Plesk manual for one line of code, this can't be that hard, surely! Thanks for any pointers, H

• Toshiba laptop cd drive read causes OS to totally freeze

  - by Fujishiro

  Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

• Workstations cannot see new MS Server 2008 domain, but can access DHCP.

  - by Radix

  The XP Pro workstations do not see the new replacement domain upon boot; they only see their cached entry for the old (server 2003) domain controller. The old_server is not connected to the network. I have DHCP working with the same scope as the old_server. In my "before-asking" search for a solution I came across the following two articles, and I recall doing things as suggested by the articles. http://www.windowsreference.com/windows-server-2008/how-to-setup-dhcp-server-in-windows-server-2008-step-by-step-guide/ http://www.windowsreference.com/windows-server-2008/step-by-step-guide-for-windows-server-2008-domain-controller-and-dns-server-setup/ The only possible issue is: I was under the impression that the domain netbios needed to match the DC's netbios. The DC netbios is city01 while the domain's FQDN is city.domain.org (I think this is mistaken and should have been just domain.org) But, the second link led me to a post which I believe answers my question. I did as they instructed by opening Local Area Connection Properties, then selecting TCP/IPv4 and setting the sole preferred DNS server to the local hosts static IP (10.10.1.1). Search for "Your problems should clear up" for the post I'm referencing: http://forums.techarena.in/active-directory/1032797.htm Have I misunderstood their instructions? I am hoping to reach the point where I can define users and user groups. Also, does TechNet have a single theoretical overview document I could read. I really don't like treating comps as magic. I will be watching this closely and will quickly answer any questions. If I've left anything out it is because I did not know it was needed. PS: I am loath to ask obviously basic questions, but I am tired and wish to fix this before tomorrow. Also, this is my first server installation, thank you for your help.

• Can't access server on LAN new Router

  - by RMDan

  Earlier this week my roommates decided to change the router we are using for our home network. On the old router I had no problems accessing a laptop running Mint Linux over the network(SSH, FTP, and Shared Folders). However I am now not able to connect. I have verified the IP address of my Linux machine has not changed and I have no problems connecting to our NAS(WDMYCLOUD). The new router is a D-Link DIR-868L. PuTTY is giving me a Timed Out error(was giving me a EHOSTUNREACH before). Running Windows 8.1 the connecting laptop, but tried connecting using my phone via SSH did not work either. More information: Can ping the Linux machine from the router but not my computer. Pinging 192.168.0.111 with 32 bytes of data: Reply from 192.168.0.102: Destination host unreachable.

I suspect that there is a permissions issue with a particular file somewhere, however I have checked the permissions of all my Cygwin binaries, DLLs and the particular files important to Cygwin sshd, including all of: /etc/passwd /etc/group /var /var/log/sshd.log /var/empty Others who have reported this or similar errors appear to have missed one of the points enumerated above. Can anyone point me to a possible solution?

• Openfire on EC2 with Jingle

  - by Bjorn Roche

  I would like to run Openfire (or another XMPP server) on EC2. At the moment this is just for testing, so easy setup and configuration are important, as is low cost. At some point, however, if things go well, it will be important to scale this. Ideally, it would be nice to not have to switch software when the scaling happens, but if a switch needs to happen later it certainly can. My requirements are: basic XMPP services, including muc and pubsub. Logins controlled from an external API. Preferably, when a user attempts to connect, the XMPP server checks with the api to see if their username and password are correct, but I can also have the API keep the XMPP server up to date on new users, deleted users, pasword changes and so on. I see Openfire has a "user service" API. Not ideal, but it looks workable. Jingle, including relay and STUN. It's not at all clear to me if the Jingle Nodes plugin takes care of this. I'm a bit confused about what's required to set this up, and I'd rather know in advance than be confused along the way :). eg It seems like STUN servers require more than one IP address. Can Openfire do all this for me, including stun and media relay on a single machine? Is this hard to configure on EC2 with Openfire? What are the basic steps? Would this be easier with something else like, say Tigase? What about database? Should I use amazon's database service, or run a db on the same machine? Would the server be compatible with a service like http://www.siteuptime.com/ Thanks!

• Windows xp mapped drives disconnect from Windows 7 on Peer to Peer network

  - by Kathryn Codo

  I have a 5 user peer to peer network. 2-XP machines, 3- Windows 7 machines and a Windows 7 machine acting as the file server. I have NO issues with the Windows 7 machines staying connected via the mapped drives to the "server". However, once a day the 2 XP machines will not connect to the Windows 7 machine "server" via the mapped drives. I must restart the "server" in order to see the server and access the files via the mapped drives or Explorer. I have tried the persistent : yes command in NET USE, on the XP machines and also setting a static IP address on the "server". I've turned the firewall off on the "server:, no difference so I turned the firewall back on. No interruption occurs with the internet when this happens, just can't see the server. Again, the Windows 7 users are unaffected. I have gone into the advanced network settings on the "server" and added read/write permissions for Everyone as well as the users of the XP machines. I have double checked that we are all on the same WORKGROUP. I'm at a loss. It seems to happen around mid-day and I've not been able to find any activity that is happening at this time (Like someone plugging in a thumbdrive). Any suggestions would be greatly appreciated as my client is running old XP software he no longer has the disks for and needs for his engineering firm.

• Windows Server 2003 DHCP not handing out IPs

  - by SnOrfus

  I'm trying to setup a home server (to tinker with) as a domain controller. I've setup the domain and I've installed DHCP and setup a scope without any exclusions (with the default range of 192.168.0.1-254). My client machine is a Windows 7 (RC) machine and it has a connection but can't get an IP address. Even if I try setting the IP to a static 192.168.0.2 and there is still no connectivity. I can ping it from the server, but pinging the server from the client just times out. The only thing between the server and the client is a 24 port switch (D-Link DES-1024D). edit Ok, it turned out that the interfaces were setup backwards in the NAT settings (the internal nic connection was set to public and the external nic connection was set to private). I changed this and all was OK.... sort-of. Problem is now: If I set a static ip on the client (where I am typing this from) all is fine. BUT; when I set it to get it from DHCP, I get a correct IP from the server (192.168.0.2) but there is no internet on the client; but I can still ping the server fine from the client (which makes sense cause I was able to get an IP from it). edit I ended up just removing the Routing and DHCP server roles and just going with ICS for the time being until I get my hands on some better learning tools.

• NTFS: Deny all permissions for all files, except where explicitly added

  - by Simon

  I'm running a sandboxed application as a local user. I now want to deny almost all file system permissions for this user to secure the system, except for a few working folders and some system DLLs (I'll call this set of files & directories X below). The sandbox user is not in any group. So it shouldn't have any permissions, right? Wrong, because all "Authenticated Users" are a member of the local "Users" group, and that group has access to almost everything. I thought about recursively adding deny ACL-entries to all files and directories and remove them manually from X. But this seems excessive. I also thought about removing "Authenticated Users" from the "Users" group. But I'm afraid of unintended side-effects. It's likely that other things rely on this. Is this correct? Are there better ways to do this? How would you limit the filesystem permissions of a (very) non-trustworthy account?
