I have recently set up PRTG's packet sniffer sensor for bandwidth monitoring. I am able to pull up historical data in 15 minute increments and see who was the highest user but I would like to see which IP was the highest user over, say, 48 hours.
As far as I can tell, I am only able to see overall bandwidth usage for anything more than 15 minute increments and not per IP usage. Is there a way to do this?
I am rolling out a disallow all Software Restriction policy on my network. I am studiously whitelisting all programs we use as I go. One issue I have is allowing .exe to run from the CD Drive. My users receive CDs from various places and need to be able to run them but I am at a loss on how to whitelist them. Does anyone have a solution?
I cant do a hash whitelist and allow certain exes because we will get new ones on a regular basis and users cant wait for IT to allow it.
I thought about doing a path rule to allow anything on the D:\ drive but I'm worried this wont work because the cd will copy temp files to pc and those will be blocked. (I am testing that now). That also isn't the most elegant solution. I am working towards unified hardware but I can't guarantee the D:\ will always be the CD drive.
Unfortunately, Google has not been much help on this particular problem
I have 3 HP Procurve 2510G-48 and I want to setup a VLAN for public wifi (VLAN100). Originally I just had the default vlan1. I have computers communicating across switches on VLAN100 with static IP addresses just fine. The problem is getting DHCP from a server on VLAN1. When I go into a procurve to setup an ip helper-address I get the following result:
ProCurve Switch 2510G-48(vlan-100)# Ip helper-address 10.4.20.251
Invalid input: helper-address
All documentation I have read says this command should work.
I'm trying to restore from tape and I am getting an error of incorrect block size. The software I used to backup is called BackupAssist and their support hasnt been the greatest. One weird thing I noticed, after updating the tape drive drivers the block size showed as 512 in the device manager. After running the restore process the block size shows up as 16384. I assume I need to get the block size on the tape drive to match up with the block size on the tape. Anyone have any ideas?
OS: Windows Server 2008 Standard SP1 64 bit Backup Software: BackupAssist v6 Tape Drive: Quantum DAT72 SCSI
So I have a weird bug that pauses the netlogon service periodically on my primary domain controller. When this happens users cannot log in to the domain. I have a secondary DC offsite that is a Global Catalog and DNS server but it is reachable through an MPLS connection.
DC1 has all FSMO roles and is located with most client PCs in the 192.168.1.0/24 network. The offsite DC is fully reachable through its dns name and sits with a few clients in the 192.168.2.0/24 network.
Why wont DC2 take over log on responsibilities when DC1 is unavailable?
I have a GPO set to force a password expiration every 90 days. I want to make an exception for one particular user so I checked the box for "password never expires" under their account properties in active directory.
I thought that made sense but today they got a warning that their password would expire in 2 days. What am I missing?
I have a point to point wireless connection using two mikrotiks. When I plug the mikrotik into a switch with just my laptop I get an IP address conflict on my machine no matter what IP I am assigned. Using wireshark i see the conflicts are from the mac address of the mikrotik on the other end of the wireless connection. Why is it conflicting with multiple IP addresses when the router itself is assigned a single IP address with no NAT entries or anything like that? I included a little diagram to help visualize my issue
[me] [mikrotik] --------------[problem mikrotik]----(other equipment on diff subnet)
The problem mikrotik has a wan on the same subnet as my machine. The lan is a different subnet. Any ideas? When I plug the equipment into my network I get IP conflicts on a lot of different servers. Took me forever to isolate it to this mikrotik! Thanks
Oh and all this equipment has been working previously with no known changes made to the configs. It just started acting up recently.
I have ran into a 10.10.50.0/20 network that is having issues with packets dropping. They run all unmanaged switches and I imagine the huge amount of devices on one subnet is causing issues.
I've looked at breaking the network down into separate VLANS but the cost of Layer3 switches is too high. What options do I have? They use all unmanaged switches and an NSA 2400 sonicwall.
If my sonicwall NSA 2400 was to ever die I want it to automatically failover to the old PRO 2040 it replaced. Is this possible with two different generations of Sonicwall? If so, what things do I need to take into consideration? My Google-fu fails me so far. Thanks!
I am having a problem with random webpages not loading. I started a continuous ping to Google DNS 8.8.8.8 and get a lot of time outs. I manage a LAN of about 100 computers. We are running a few 24 port unmanaged switches going through a Sonicwall NSA 2400. Here's the network:
Computers -> Switches -> Sonicwall -> Internet
The test I do is just continuous ping to 8.8.8.8 from my laptop. I plugged directly into the ISP router and it works fine. If I remove the network and just plug directly into the LAN side of the Sonicwall then everything works fine there. But as soon as I plug in the network switches I get a lot of timeouts. I am planning to reboot all switches later in the day but I was wondering what other troubleshooting steps I can take if that doesnt fix it. I plan on unplugging everything and slowly plugging things in one at a time to find the problem but I wonder if there is an easier way. Is my sonicwall just messing up because of the amount of traffic or is there something on the network causing the issue like a broadcast storm type situation
I run merak mail server using pop3 and wanted to look into setting up blackberry enterprise server express. Will this work with simple pop3 accounts? If all your calendars are stored locally in outlook how does that work with BES? Thanks. I have a feeling I need to get a different mail server to really get all the features.
I am hosting a Merak e-mail server for our domain example.com. Everything works great accessing the server from outside the network using mail.example.com for ingoing and outgoing servers. However, clients on the same LAN as the mail server get the error "Outlook cannot connect to your outgoing (SMTP) server"
I have to set the Outgoing server to the internal DNS name or internal IP address of the mail server. This really sucks for our laptop users that move in and out of our network. My question is how can I fix this? Users are able to access webmail using mail.example.com even when in the network so I am thinking this is a setting in merak somewhere.
According to adaptec support site, data on a disk got corrupted. The disk is physically fine and thats why it shows up as optimal. The solution is to reinitialize the disk. The only problem is I can't figure out which disk has the problem. Adaptec Storage Manager just says raid is degraded and all disks are optimal with no more information. Any ideas?
