Our LAN uses 192.168.1.x IP addresses.  One of our vendors has just required us to connect to their VPN, then RDP to one of their computers to conduct business.  Their network also uses 192.168.1.x IP addresses.  Our network is small, so the effects have been minimal, but only by luck it would seem.  Sometimes we are forced to re-login to our own file server, and this is cumbersome and inconvenient.  How can we adjust settings on our end to minimize/eliminate IP address conflicts?  Our networking equipment is SOHO.  One perhaps obvious solution would to change our entire subnet internally, but that just doesn't seem like the best way to proceed.  Advice please?

I am needing a revolving server system that changes IP address once it starts getting hits from sever filters. It needs to be seamless and use the same email address that we establish to send emails out from, but configures a different IP with every 50 to 100 emails. This is what we need to get a marketing job done and the email messages we want to send have to fit the character count specifics and font type. The subject line is the most important and the size cannot exceed X kilobytes for the total email to reach target market.

What are the best methods to translate or determine what an IP v6 address equivalent IP v4 address is?

If I have 2 domain controllers in 2 different sites and both have IPv6 checked in TCP stack, do I need to define the dynamic IP address in AD Sites and Services?

I had an issue with SYSVOL GPO replication where one of the domain controllers was using the IPv6 address of the other domain controller to access its SYSVOL, but the address was not defined in AD Sites and Services.  I unchecked and did some other things that resolved the issue... but I need to know best practice for this please. thank you.

Single Server 2012 R2 network w/40 Win7 PC's.  All "appears to function just fine but continually getting DNS - BPA reports "DNS Servers on Ethernet should include the loopback address, but not as the first entry".

NIC is configured:
Preferred DNS Server:  192.168.16.4
Alternate DNS Server:  127.0.0.1

I've tried different combinations of these addresses.  Should I have our ISP's DNS server settings as primary?

I confess I'm no DNS expert, nor do I know anything about actively managing an IPv6 network.  I can find my way around IPv4 and basic DNS functions just fine.

Connection has  “Microsoft Network Adaptor Multiplexor Protocol” unchecked.  Unsure if this is a default setting or if done as part of earlier diagnostics.  Will follow best practices.

Unsure if it is related but all workstations on the network are Windows7 Pro.  Most of them show a yellow exclamation mark on the network icon in the task bar and “no Internet” although the Internet connection is just fine.  I disable IPv6 momentarily and the exclamation mark goes away.  I reenable IPv6 and the exclamation mark stays gone until the next reboot.

Any assistance appreciated.

Recently, our W2012R2 RDS server has started giving users problems logging in. The message is:

The number of connections to this computer is limited and all connections are in use right now. Try connecting later or contact your system administrator.

I'm having a hard time finding any helpful information on how to resolve this issue other than on desktop versions of Windows.

In a bid to get around this issue, I've opened more ports (HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp 339x), and this has given some temporary reprieve.

It seems to me that the issue is pervasive. By that I mean that the message does not disappear even if existing users log off from their RDS sessions.

This RDS server has been working fine for years, and now, suddenly, this happens.

Please include the detailed explanation of the following:
Physical layer
Data link layer
Network layer
Transport layer
MAC address
IP address

Hello All,

I have integrated Kamailio 4.4 with asterisk 13 LTS and I think its been properly integrated. It also shows me the registered users but when i call from 101 to 102 it gives me the below error

[May  7 12:43:14] NOTICE[19838][C-00000000]: chan_sip.c:25545 handle_request_invite: Call from '101' (192.168.56.103:5060) to extension '102' rejected because extension not found in context 'public'.

I have followed the below for installation and configuration.

http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb

The user database is fetching from remote host in which kamailio has been installed. Users are showing in asterisk node as well

asterisk*CLI> sip show users
Username                   Secret           Accountcode      Def.Context      ACL  Forcerport
101                                                          public           No   No
102                                                          public           No   No

So how can i debug this or is there any clue that what might be wrong. Please find below  the extension.conf details as well.

exten => _1XX,1,Dial(SIP/${EXTEN})
exten => _1XX,n,Voicemail(${EXTEN},u)
exten => _1XX,n,Hangup
exten => _1XX,101,Voicemail(${EXTEN},b)
exten => _1XX,102,Hangup

Thanks and looking forward for some clues from this community

Public IP configuration for two different network. I got error when I assign public ip address on port 1 and 2 with same subnet. 1.1.1.1/24 for port 1 and i got error when I try to set up 1.1.1.2/24 on port 2, "same subnet on port 1" I am using Cisco 1926.  How do I make this work? Any advise?

I'm sure this is simple, but I can't remember and I don't have time to figure it out, so...

I have a Windows 10 "All In One" lenovo computer.

The PC needs to connect to a small personal NAS via Ethernet, AND, the only way it can get Internet is Via Wireless.

The PC has both wireless and Standard RJ45...

I just can't remember how to do both at the same time.

Or, am I over thinking things: Just set a common IP for the RJ45 and the NAS , and then connect the wireless and I'm done...

Just not sure, and when I get there to set it up, it'll be too late to figure it out.

Thanks!

could I have 2 incoming skype phone numbers

can I receive (not send) sms to skype united states phone number

Ground Phone line number. How can I opt out of receiving text to landline messages.

Do I need to opt out for 1 phone number at a time

Does COMCAST have poor quality phone service?

I switched yesterday from Verizon FIOS to COMCAST and had terrible telephone calls today on the land line.

I think we were sold >100 GPS upload speed. So, I doubt the poor quality is due to a slow internet connection. But maybe the old Verizon FIOS phone number was what they called a POTS line, a Plain Old Telephone Service line. Those were the ones where you cold hear pin drop.

Did I move from a POTS Line to an Internet based phone? And is that the cause of the major drop in quality?

My new modem is...

Xfinity
Dual Band Wifi
802.11.ac

The phone cable goes into the back.

Would an Internet phone do better?

Is there anything I can do?

I really despise having poor phone quality and may go back to Verizon to escape a bad connection.

Suggestions?

Thanks
