  • Web SMTP Server(foo.com) will not send mail to exchange server which is also(foo.com)

    - by Atom
    I think I understand this problem fully, but I do not know how to approach it or where to go in terms of troubleshooting. I've got my one domain http://foo.com that runs a Zen Cart installation that needs to be able to send emails to users(order confirmation, password reset). This works fine to send to any other domain BUT foo.com. I'm running a locally hosted exchange server that is foo.com, and we can send and receive email just fine. If I run tail -f /usr/local/psa/var/log/maillog I recieve this error: Apr 1 10:08:51 foo qmail-local-handlers[25824]: Handlers Filter before-local for qmail started ... Apr 1 10:08:51 foo qmail-local-handlers[25824]: from= Apr 1 10:08:51 foo qmail-local-handlers[25824]: [email protected] Apr 1 10:08:51 foo qmail-local-handlers[25824]: cannot reinject message to '[email protected]' Apr 1 10:08:51 foo qmail: 1270141731.583139 delivery 32410: failure: This_address_no_longer_accepts_mail./ Apr 1 10:08:51 foo qmail: 1270141731.584098 status: local 0/10 remote 0/20 I understand that the foo.com SMTP service doesn't have any account but the one that is used to authenticate mail being sent, so of course, I understand why it's saying 'this address no longer accepts mail'. My question is, how can I get the foo.com(web) SMTP service to handle emails meant for my exchange server([email protected]) or how do I handle the mail that needs to be sent to our exchange server? Is this something to do with MX records? Thanks in advance A

  • Need to get SMTP server on MS Server 2003

    - by Matt Dawdy
    Long story short, client paid networking company to move their website in house. Now I have to figure out how to email out from their website even though they don't have an SMTP server. At least until I install one. Their email is hosted with Gmail right now (the client's domain through Google App for Your Domain). I changed my code to connect as one of their users "[email protected]" and send email. Worked great for about 12 hours. All of a sudden none of the automated emails are going out now, and google is sending the emails back saying that it is a permanent failure and Message Rejected. The link they direct me to, http://mail.google.com/support/bin/answer.py?answer=69585 is telling me that our emails look like spam. They aren't. They are emails we send to out clients about the status of their applications. Seriously, they are NOT spam. So...long story short is out the window, sorry...but I need to get an SMTP server setup inside their domain that I can send emails out of. This thing won't need to receive emails ever, and really only needs 1 email account customercare. What can I do? Will I have to have the networking company open a port in the firewall? Is there one built into Server 2003?

  • Unable to connect to shared (iscsitarget) dvd-rw drive on ubuntu karmic box

    - by Develop7
    Intro I have desktop with DVD-RW drive that runs primarily on Linux (namely Ubuntu 9.10). My wife has netbook that rins Windows XP with no cd/dvd drive. There's also LAN through our ADSL modem/router. I've "ported" (actually, I've just grabbed sources and ran dpkg-buildpackage) iscsitarget package from Ubuntu Lucid to Karmic (here are packages), installed it (sudo aptitude install iscsitarget; sudo m-a a-i iscsitarget) and configured it in the following way (/etc/ietd.conf): Target iqn.2020-01.local.develop7-desktop:storage.disc.dvdrw Lun 0 Path=/dev/sr0,Type=blockio #I've skipped commented lines Also, I've opened port 3260 with ufw: $ sudo ufw status | grep 3260 3260 ALLOW 192.168.1.0/24 Problem But (here's the trouble) I still can't connect to this target from Windows box. Microsoft Software iSCSI Initiator screams "Logon failure" upon connect attempt, and, respectively, fails to connect. After unsuccessful connection attempt I've noticed this line in dmesg | tail's output: iscsi_trgt: ioctl(299) invalid ioctl cmd c078690d Question So the question is — what's wrong with my config/iSCSI target/whatever else? Or, in short — what I'm doing wrong? Thanks in advance.

  • How do I determine whether this email bounce is my fault?

    - by David Zaslavsky
    I use Google Apps to handle email for my personal website, so I have an email address [email protected] through that, and I also have a Gmail account [email protected]. Now, I've been trying to send emails to a particular recipient who shall be known as [email protected]. When I send the email from my Gmail account with the @gmail.com address, it works fine. However, when I send it from my Google Apps account with the @ellipsix.net address, I get a bounce message which includes the following text: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 mail server permanently rejected message (#5.3.0) (state 17). The bounce message suggests that it is up to the mail administrator of the recipient domain example.com to fix the problem, whatever it is. But I would like to be as sure as possible that nothing needs to be fixed on my end. I already have DKIM signatures enabled for my domain, and I have published an SPF DNS record. Is there something else I should check or do, or can I be confident that it's up to the recipient to fix this issue? Does the "state 17" in the bounce message mean something relevant? I've included my domain name in the question so people who know more than me about this stuff can independently check the relevant DNS records or other information. This other question seems similar, but I've already investigated everything suggested in the answers there (except for contacting Google, which I don't want to do unless I suspect it's their issue to fix).

  • error in auth.log but can login; LDAP/PAM

    - by Peter
    I have a server running OpenLDAP. When I start a ssh-session I can log in without problems, but an error appears in the logs. This only happens when I log in with a LDAP account (so not with a system account such as root). Any help to eliminate these errors would be much appreciated.

  • Secondary backup server

    - by verdy
    I've been given a task to implement a backup solution in the event of our website goes down. It is a dedicated server running centos 6. From what i've experience on our server, our server may go down because of PHP application crash or hardware failure. I have couple of questions: In the first case, is it possible to get the server restart the PHP automatically, how can I do that? Because in my mind, if it is only the application that goes down, probably I can still make use of the server itself. In the second case, can I redirect a request to a secondary server? How can I do that? What do I need other than another server? For now it is gonna be a simple server which shows the user a static landing page so later the system notify us via email that the primary server went down so that we can restart the server manually. Is it possible to setup just a vps or even a shared server for the secondary server ? As I think there is only gonna be a static page. Thanks. Any help would be much appreciated

  • Error in Bind9 named.conf file. Bind won't start.

    - by tj111
    I'm trying to setup a DNS server on an Ubuntu Server machine (10.04). I configured an entry in named.conf.local to test it, but when trying to restart bind9 I get the following error: * Starting domain name service... bind9 [fail] So I checked the output of syslog and this is what I get. May 20 18:11:13 empression-server1 named[4700]: starting BIND 9.7.0-P1 -u bind May 20 18:11:13 empression-server1 named[4700]: built with '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--sysconfdir=/etc/bind' '--localstatedir=/var' '--enable-threads' '--enable-largefile' '--with-libtool' '--enable-shared' '--enable-static' '--with-openssl=/usr' '--with-gssapi=/usr' '--with-gnu-ld' '--with-dlz-postgres=no' '--with-dlz-mysql=no' '--with-dlz-bdb=yes' '--with-dlz-filesystem=yes' '--with-dlz-ldap=yes' '--with-dlz-stub=yes' '--with-geoip=/usr' '--enable-ipv6' 'CFLAGS=-fno-strict-aliasing -DDIG_SIGCHASE -O2' 'LDFLAGS=-Wl,-Bsymbolic-functions' 'CPPFLAGS=' May 20 18:11:13 empression-server1 named[4700]: adjusted limit on open files from 1024 to 1048576 May 20 18:11:13 empression-server1 named[4700]: found 4 CPUs, using 4 worker threads May 20 18:11:13 empression-server1 named[4700]: using up to 4096 sockets May 20 18:11:13 empression-server1 named[4700]: loading configuration from '/etc/bind/named.conf' May 20 18:11:13 empression-server1 named[4700]: /etc/bind/named.conf:10: missing ';' before 'include' May 20 18:11:13 empression-server1 named[4700]: loading configuration: failure May 20 18:11:13 empression-server1 named[4700]: exiting (due to fatal error) So it thinks I have an error in the default named.conf file, which is pretty ridiculous. I went through it and deleted a blank line just for the hell of it, but I can't see how it figures there's an error in there. Note that before this I did have an error in named.conf.local, but it showed up properly in syslog and I fixed it, so it is reporting the correct file. Here is the contents of named.conf: // This is the primary configuration file for the BIND DNS server named. // // Please read /usr/share/doc/bind9/README.Debian.gz for information on the // structure of BIND configuration files in Debian, *BEFORE* you customize // this configuration file. // // If you are just adding zones, please do that in /etc/bind/named.conf.local include "/etc/bind/named.conf.options"; include "/etc/bind/named.conf.local"; include "/etc/bind/named.conf.default-zones";

  • Laptop will not boot

    - by WillumMaguire
    This is a dell studio 1558 laptop. Now, something is wrong with the charger that it won't charge the laptop, but the laptop can turn on and operate properly as long as it is attached. It has been like this for a while, but it's not the problem. My problem is that as of yesterday, It takes several minutes to get past the "dell" startup logo (where is says "f2 setup" and "f12 boot options"). After it gets past, it beeps as normal to tell me about the charger and gives me the f2/f12 options and f1 to continue as normal. I can press f12 to get into boot options and load into my live USB BackTrack 5 ISO, but after "startx" it just stays at a black screen. I can also access BIOS setup, but see nothing that would help the problem. When I boot to the HDD, it gives me this Intel UNDI, PXE-2.1 (build 083) Realktek PCIe GBE Family Controller Series V.2.29 (06/30/09) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM Operating System not found Also, pressing f8 gives me the same results as booting as normal. It is running Windows 7 Ultimate, dual-core Intel i3 @ 2.27ghz and 4gb RAM. I think there is an issue with the HDD, as the "Operating System not found" would lead me to believe. Is this a fixable problem?

  • Failed to generate a user instance of SQL Server

    - by Goondocks
    I'm using Windows 7 Beta and trying to install a web application locally. This web site uses Microsoft SQL Server 2005 Express (SQLEXPRESS) and a MDB file in the web site's ~/App_Data folder. I was instructed to configure IIS7 to use Classic .NET AppPool for this web application. Each time the web site loads, I receive the following error: There was an error trying to connect to the Database Server: Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. The Internet is packed with articles written on this subject. The prevailing wisdom seems to be: Configure the SQL Express Service to use the Local System account. Delete the following directory: C:\Users\username\AppData\Microsoft\Microsoft SQL Server Data\SQLEXPRESS Neither of these fixes have made any impact. I have tinkered with permissions and settings for hours to no avail. Can anyone suggest a fix or help me understand how to get more detailed information about the problem.

  • Issue booting Linux Mint from Live CD?

    - by Vee
    I had Windows 8 and Linux Mint 15 dual booted on my laptop. When I first installed Linux, I wasn't able to load into because the grub would not show. To fix this, I used boot-repair from a Live CD. This time, I updated to Windows 8.1 and it showed a watermark telling me my secure boot wasn't configured properly. I then went and enabled secure boot (BIOS) and I believe it was after that that the Grub would not show once again. I tried to boot from a Linux CD again but when I try, it gives me the following errors: error: failure reading sector 0x0 from 'hd1' error: you need to load the kernel first. Press any key to continue... Before, it was giving me an error with sector 0x6d200 or something instead of 0x0. I am completely unsure of what to do. I do not know what other details to give except that this my have happened after I enabled secure boot, and I actually clicked reset to default setting so I am unsure if any other settings were changed in the BIOS menu.

  • How to re-join an AD2003 domain with Samba after deleting the machine account?

    - by Guss
    During some troubleshooting I deleted the machine account for a Linux server running samba from our AD 2003 domain. We are using Kerberos for authentication, and after I deleted the machine account I tried to join the domain again using net ads join -U Administrator But I keep getting Kerberos errors like these: [2009/08/18 16:14:36, 0] libads/kerberos.c:ads_kinit_password(228) kerberos_kinit_password [email protected] failed: Client not found in Kerberos database Failed to join domain: Improperly formed account name It appears as if samba remembers that it once had an account with the AD and keeps trying to reconnect to it, but I want to create a new account from scratch. I tried to delete all the .tdb files I could find as well as everything under /var/cache/samba but to no avail - it still behaves the same. I also tried to create the machine account on the AD side, but then I get a similar error when I try to join, about failure to authenticate with the machine account - it looks like samba tries the previous machine account password and I don't know how to reset it, or even if I could figure out what samba uses - how to set it in the AD. Any help would be greatly appreciated, as at this point the only thing I can think about is to reformat and reinstall the machine, and I would really REALLY love to not do that. Thanks in advance.

  • Windows 8 - no internet connetction to some hosts while VPN is active

    - by HTD
    I use VPN to access the servers at work. When VPN is used, all network traffic to the Internet passes through my company network. It worked without any problems on Windows 7, now on Windows 8 some sites suddenly became inaccessible. Please note - I don't try to connect them over RDP, they are public Internet addresses, outside company network. They are inaccessible using any protocol. Ping returns "General failure.". I know it could be a misconfiguration on my company's server side, but it's very strange, since the same VPN connection used on Windows 7 works properly. What's wrong? Is it a Windows 8 bug, or is there something I could do on my company servers to make VPN work as expected with Windows 8? My company network works on Windows Server 2008 R2 and uses Microsoft TMG firewall. I couldn't find any rules blocking the traffic to mentioned sites, all network traffic for VPN users are passed through for all IPs and protocols. Any clues? UDPATE: Important - one whole day it worked. I hibernated and restarted the computer, connected and disconnected VPN - nothing could break my connection. Today it broke again, and restarting Windows didn't help. And now the solution: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.1.1 Oh, OK, I know what it did, added my default gateway to routing table. But it still didn't work sometimes. So I removed my main network gateway route with: route delete -p 0.0.0.0 MASK 0.0.0.0 192.168.0.1 And added modified with: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.0.1 And it works. Now. But I don't trust this. I don't know what really happened.

  • NFS headaches with FreeBSD 4.9

    - by Ernie
    Once upon a time, this used to work, and I kept the configuration the same, but... now nothing. I'm just trying to get an NFS server set up on a FreeBSD 4.9 server. The process should be about as complicated as this: Add this entry to /etc/exports: /var/home /var/vpopmail/domains -maproot=root XXX.XX.XX.XXX Execute this: portmap nfsd -u -t -n 4 mountd -r Then this should work, regardless of network and firewall issues: showmount -e localhost But showmount -e localhost fails with the following error: RPC: Port mapper failure showmount: can't do exports rpc And even if I kill off the NFS daemon, and try a rpcinfo -p localhost, I get this error: rpcinfo: can't contact portmapper: rpcinfo: RPC: Unable to receive; errno = Connection reset by peer The portmapper is still running. Why the heck does nothing work as if it isn't? Edit to add: FYI: Sockstat gives me this: $ sockstat |egrep "(nfsd|portmap)" root nfsd 86310 3 udp4 *:2049 *:* root nfsd 86310 4 udp4 *:973 *:* root portmap 45920 0 tcp4 *:111 *:* Then, at a later time (say, 5 minutes) it's as if nfsd isn't acting as a server: $ sockstat |egrep "(nfsd|portmap)" root portmap 45920 0 tcp4 *:111 *:* But the nfs daemon is still running: $ ps ax |grep nfsd 86311 ??

  • Email bouncing sent from Google

    - by davidmck
    I'm hoping someone here has an idea of where to look next. We have a domain we support which has email sent to it from one particular user bounce with the following message: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unrouteable address (state 14). We only have reports of bouncing form this one particular user (who is someone we don't support - except they'd like to be able to contact our customer and we're trying to figure out if the problem is on our end). Many people can successfully send to this domain and the user who is getting bounce messages can send to other domains that we support (so it's clearly something specific with the princetonscoop.com domain and not our setup in general). I've reviewed the MX records multiple times and the server logs don't show a connection which generates this error (in fact this error is not one that our mail server would ever return). So it appears that google is contacting a different mail server for some reason. I have tested sending from my gmail account and that works. I believe the sender is using a google-apps account (the account they are using is from their own domain, not a gmail account). Any ideas on what might be happening here or what to test/investigate next? Thanks.

  • Moving Farm to co-location hosting - network settings requirements

    - by Saariko
    I am moving my farm (2 Dell's R620) to a co-location hosting service. I am trying to figure out the secure way to have my network settings The requirements are: VM1 is the working HOST, includes: esxi 5.1, vSphere, 4 clients (w2008r2 all) VM2 has esxi 5.1 installed, and a single machine with Veeam Backup and copy 6.5 - keeping a copy of VM1 clients on the VM2 internal storage (this solution is due to a very small budget - in case of failure on Host 1 - can redirect IP's) Only 2 VM clients require network address and access from the WWAN - ISP provides IP's range for them (with Gateway and DNS) I need connection to the iDrac's from my office (option to create a VPN-SSL tunnel) Connection to the vSphere appliances I want to be able to RDP to the VM clients The current configuration is that each host has the iDrac dedicated nic connected , and another (NIC #1) connected - with a static IP on 192.168.3.x The iDrac's have a static IP from the same network range (19.168.3.x) It will look something like this: My thoughts: On NIC#2 of both hosts I will connected a crossed cable I will give each VM clients that needs internet access a 2ndry VM network with the assigned IP from the ISP open only to web - can not access from the My Question: Should I give IP's (external) to the machines who DO NOT require WWAN Access? - I can't see a way to RDP to them directly if not. Should I use the crossed cable? or just plug NIC #2 to the switch? Will this setup even work? What do I need to verify? What Virtual nic's and/or switches should I create on the Hosts?

  • SQL Server 2008 R2 mirroring failing

    - by andriusn
    I have two Windows 2008 R2 (Amazon EC2) instances running SQL Server 2008 R2. I use 9TB striped disks (9x1TB EBS volumes) for storage. One server is running as principal and second one as mirror. Both started from the same image, database and tlog files located on striped disk. Mirror server failed 3 times in last 2 months with errors: EventID 823 The operating system returned error 2(The system cannot find the file specified.) to SQL Server during a write at offset 0x00000048058a00 in file 'D:\TLogs***_log.ldf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. and EventID 1454 Database mirroring will be suspended. Server instance 'xxxxxxxxxx' encountered error 823, state 6, severity 24 when it was acting as a mirroring partner for database '***'. The database mirroring partners might try to recover automatically from the error and resume the mirroring session. For more information, view the error log for additional error messages. followed by EventID 19019 The MSSQLSERVER service terminated unexpectedly. After this rebooting instance is necessary to restore mirroring. First two times I thought it was hardware related (striped disk failure) and relaunched instance on new hardware. But the issue is back after few weeks again. It only affects mirror instances. Any help would be really appreciated. Thanks.

  • PostgreSQL failover cluster on Windows Server

    - by user36997
    We are looking for advice on how to setup a basic failover cluster for our application: We will be using 4 machines running Microsoft Windows Server (most probably 2003). All four will always run our application, which is essentially a web service. Load balancing is "outsourced" - somebody else handles the distribution of the web requests among the servers. Only one of the servers will be running the PostgreSQL server actively at any given time. Another server (of the four) also has the DB installed, but is on standby/passive. The DB data is stored on shared storage. No copying data between servers. Reads are done very frequently by many end-users, and in rather small chunks of data. Writes are done much less frequently, by less users, and in very large bulks of data. Now, how can one configure Microsoft Cluster Service to keep only one instance of the DB server and 4 instances (1 per server) of our application at all times? And does PostgreSQL integrate neatly with MSCS at all? Update: Instead of keeping the data on shared storage, I also consider using log shipping to replicate data on a couple of DB servers. There are two issues with this option: Log shipping only makes sure that I have a second server that gets all of the data and is ready to take over. How do I implement the actual failure detection and failover switch? Switching back: Suppose the master fails and the system automatically fails over to the slave, and later the master comes back online. I understand that with WAL shipping this will require to reconfigure the log shipping once again, and that switching back is far from seamless. Is that so?

  • Mysql, SSL and java client problem

    - by CarlosH
    I'm trying to connect to an SSL-enabled mysql server from my own java application. After setting up ssl on mysqld, and successfuly tested an account using "REQUIRE ISSUER and SUBJECT", I wanted to use that account in a java app. I've generated a private key (to a file called keystore.jks) and csr using keytool, and signed the csr using my own CA(The same used with mysqld and its certificate). Once signed the csr, I've imported the CA and client cert into the keystore.jks file. When running the application the SSL connection can't be established. Relevant logs: ... [Raw read]: length = 5 0000: 16 00 00 02 FF ..... main, handling exception: javax.net.ssl.SSLException: Unsupported record version Unknown-0.0 main, SEND TLSv1 ALERT: fatal, description = unexpected_message Padded plaintext before ENCRYPTION: len = 32 0000: 02 0A BE 0F AD 64 0E 9A 32 3B FE 76 EF 40 A4 C9 .....d..2;.v.@.. 0010: B4 A7 F3 25 E7 E5 09 09 09 09 09 09 09 09 09 09 ...%............ main, WRITE: TLSv1 Alert, length = 32 [Raw write]: length = 37 0000: 15 03 01 00 20 AB 41 9E 37 F4 B8 44 A7 FD 91 B1 .... .A.7..D.... 0010: 75 5A 42 C6 70 BF D4 DC EC 83 01 0C CF 64 C7 36 uZB.p........d.6 0020: 2F 69 EC D2 7F /i... main, called closeSocket() main, called close() main, called closeInternal(true) main, called close() main, called closeInternal(true) connection error com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure Any idea why is this happening?

  • I need an admin toolset for Windows 2003 and 2008

    - by eugeneK
    i know this is way too general question but anyway. I need few tools, will write down my tasks as sysadmin and if you have any to automate my job i would be glad to hear. I don't mind paying for software needed unless it is way too expensive. First of i backup all files on server at local/office storage. I 7zip all SQL backup files and then move them over network to centralized location and then FTP them from office PC which has no FTP server installed and cannot have one. Backups happen at 4AM at the morning thus i need to set time for compressing and afterward FTPing. Then i FTP all IIS web application as differentiation backup, same goes for VOD movies. Second tool i need is system monitor which will monitor all servers from themselves and from external location for CPU/Memory/Hard disk and other basic failures. This tool should able to execute Website address with parameters which will send me an email with all report on failure. Third tool i need is a way to get all Event Logs from 10 Windows based servers without accessing each any of them manually. If you know any solution, thanks in advance.

  • VNC server failed to start CentOS

    - by Shaun
    I followed a tutorial on how to install and get VNCserver to run on CentOS 6 (since freenx isnt supported yet) and I keep getting Starting VNC server: 1:user [FAILED] How do I figure out whats going on here? Im new to Linux/CentOS and im trying to get RDP going so I can step away from SSH as much as possible (you know us Windows users love our pretty GUI's). So, where is the error log at and how do I find it? Or maybe someone else has experienced this and knows the solution based on the simple error given?

  • Drobo FS vs Lime Technology unRAID vs FreeNAS

    - by elluca
    I already decided to by a drobo fs until I just found these two tests: http://www.digitalversus.com/data-robotics-drobo-fs-p889_9543_487.html http://www.digitalversus.com/lime-technology-unraid-p889_8992_473.html The two cons agains drobo for me: loudness price What disadvantages has the unraid stuff against the drobo fs? Has it also got that ease of use like swapping drives on the go, simply extend capacity by plugging in new drives, notify me of drive errors, disk failure protection, dynamic space of "partitions", better/worse effective capacity, etc. Which is more secure? Am I able to simply replace a bad drive with a new one on unraid? What happens if my pc fails? Lets say the cpu overheats. Since I have a complete pc which is going to be replaced, I only have to pay the software to use unraid. I am going to use my nas for: music library (how well does it integrate with iTunes? ) picture library movie library development (i need to be able to be to use time machine) I am going to use this nas with a MacBook pro. My current disks: 2x 500Gb 1x 1.5Tb 1x 2Tb On a drobo fs I would have 2.26 Tb of space. What would it be on unraid? Is FreeNAS also an alternative?

  • Possible DNS issue after a reinstall of Windows Server 2000 (get off my lawn)

    - by cop1152
    I just replaced a drive on a Win2000 Server that replicates AD and issues out DHCP at one of our offices. I successfully joined it to the domain, setup range of IP's, etc, but am still having issues. I cannot RDC to it with name or IP. I can ping it, browse to it with Windows Explorer, and remote to it with some other software, but not RDC. The other issue is this: Users are unable to authenticate on it. They receive the message 'username or password incorrect' (or something like that). Changes made on the main domain controller seem to take forever to trickle down. The most significant entry in the DNS Server Log is Event ID 7062: The DNS Server Encountered a Packet Addressed to Itself. At least, I think its significant. The Directory Services Log shows numerous Event IDs 1265: The attempt to establish a replication link with parameters failed with the following status: The DSA operation is unable to proceed because of a DNS lookup failure. Does this make any sense to anyone? I feel like its something very simple that I am overlooking. Thanks in advance.
